CH341A EEprom Programmer Review and Practical Use Instrument Cluster Repair
HTML-код
- Опубликовано: 11 июл 2024
- In this video I take a look at the cheap CH341A eeprom programmer. I show practical uses of it on GM instrument clusters. We also take a look at a commonly done modification to the programmer. The CH341a USB flash programmer can also be used to read or write a motherboard BIOS or any other EEprom supported by the software.

Please watch the follow up video here: ruclips.net/video/FAYVpxnvYk8/видео.html
you're a life saver. I spent two hours just trying to find the right drivers & other goodies that go with this programmer. Have a Merry Christmas
Well put together and informative. The wry humor is a bonus, so thanks and well done.
Glad you enjoyed it!
Thanks for walking me through the software process.
I bought one of these to convert a chromebook to uefi for windows, had no idea it could be used on my cluster. Thank you!
Great video Matt. Might have to pick one of these things up in the future.
You should but be aware the drivers don't seem to work the first time you install them so be ready to mess with that. I've got a few emails from people having issues with drivers and I am not an IT guy lol
Impressive you were actually able to read/write to the chip. With the display in the way and on the board I never had any luck. I always remove the chips and use the adapter instead. I also don't like bending the pins on the VFD to get the clips on. Good content!
Agreed I only use it on 05 and 06/07.03/04.i just pull the chip
Couln't read a bios chip till I watched this video...Your idea of stuff pullung the voltage down made sense so I tried it without the 1.8 adapter with the chip in circuit... It worked! I was able to remove password and write the chip. SMJ 23
Great video dude!
Thanks!
Thanks for class.
You are absolutely correct, to operate this in 5v mode all you do is fit a jumper across the 3.3v and 5v rails on the pin header, effectively bypassing the 3.3v regulator completely. No need to lift any legs , cut tracks or solder anything.
Yeah when another technician pointed me to his video when saying I should test out that programmer I was confused why he did that before even getting my hands on it. I the. Guessed the ch341 ran at 3.3v with 5v tolerant GPIO but once I got it I knew that wasn't the case. I then also realized my logic in thinking wad faulty since he lifted the 3.3v pin. (While leaving the other 3.3v pin on the board). Idk if that top pin is actually populated on the board or just a blank pad though
@@FixedUntilBroken You are correct the large pad is still connected to the 3.3v rail so lifting the leg will make absolutely no difference. I've confirmed continuity with a DMM, also with the leg lifted there is still 3.3v on the pad.
@@FixedUntilBroken
The ch341a programmer is designed to work at 5V.
Switching to 3.3V has a flaw: 2 jumpers are needed to do it right not only 1.
In datasheet of ch341 is specified that output signals levels are at Vcc-0.5V.
On the other hand, those signals levels defines how inputs / outputs are translated to 0, 1 and undefined binary states. Usually (Vcc / 2 )-/+ 0.5V means undefined state.
Programming a 3.3v IC with 5v might fail because programmer might send on ouput a 2V-1.5 V signal (0 state) and the 3.3V IC might interpret that like 1 binary state or undefined binary state.
Only because it's works doesn't mean that is right way to do it.
@@contacttly6398 I think you are missing what we are doing here. We are working with automotive ICs that are 5 volts and need the tool to work at 5volts. From the box it's set up for 3.3v . I have no need for the ch341 to work at 3.3v. I need 5 volt. Btw if you expect no errors out of $5 I suggest lower expectations or a larger budget.
I do a appreciate the information we just aren't using at 3.3v
This board actually has a bigger issue. It really doesn't have anything to stop you from frying the ch341a. I was testing a hand held soic8 pogo pin and slipped with it and the magic smoke came out of my ch341a.
Interesting that when used 5V jumper it was very hard to read automotive chip in place but switching back to 3V an it reads everytime. So not always 5V is better.
Just ordered me one last night. Looks like I'll be having trans temp here soon.
Could you make a video on how to do it on a 06 with this device. Thanks again. Love the videos.
Thanks for the vid. The vid you talk of renewed my search to smoke electronics.. Once I got my programmer it just looked like a jumper would work, It did, so no rewire mod for me. The chip clip gave out about the time I started to figure out what I was Kind of doing. My big hurdle is figuring out what the EEproms are VRS the labeling on them. Didn't even consider that other rail to wire the chip reading ability.. thanks again.
GLad I could inspire you. yeah you just have to replace those stupid clips every so often. I hope I can find to to make a bed of nails (pogo pin) project. Should be a lot more reliable than the clips.
Thats been my Go-To for a while. Using the header pins with leads that I'll then solder onto the back of the 99-02's daughter board works great! I agree, those clips suck, I just buy them in bulk.
I've been hearing grumblings around that these are the best thing since sliced bread so I had to try it.
27:00 the PCB is for external 24Cxx EEPROM for config read on reset. It can be customized using CH341CFG, change VENDOR, PRODUCT ID and serial and mode without hardware jumper.
Good video. What would I change to add trans temp on the cluster?
Great video
Question , what should the ch341a look like to read 93cxx eeprom chips with the test clip ?
What do I need to connect to get this reading done
Hopefully you guys find this useful. I did mean to say that 3.3v could potentially get pulled down lower than 2.5v not 5v ( the ST95020 will work from 2.5v to 5.5v). Not picking on Dr Shock I just know people do this mod all the time based on google and what Raul told me about it.
Do you have a link where I can buy the leds you use on clusters ?
In the video you are referring to, he is doing the 5v mod because there is a flaw on the CH341 that he has. I had to watch it a couple times to catch what he is saying. Start at 5:35 and he shows that he does not have 5v on pin 1, which he says you need for automotive work. On my CH341, the 5v pin is connected to pin 1, so if I use the jumper, I get 5v on the pin 1.
I've used this for quite a while and finally broke down and bought obdstar x300m and use it on a obd2 port added to my bench harness and it's much faster... However, you will still have to use the eprom reader/writer if changing vin/adding transmission temperature gauge..
Hey, just came across this while watching DrShock's video. I'm looking to program a 93XXX chip that needs 5V apparently, you mention that I can just add a jumper but in the video at one point you said add a jumper between the 3v a d 5V to give it 3V. So is it 5V with the jumper inserted or not inserted ?
If you Jumper 5v with 3.3v you get 5v. if the jumper is off you get 3.3v at the power pin. Not to confuse you or anything but the data pins are always at 5v due to poor design of this board. its only the supply voltage pin that changes.
Bro, I'm struggling to get a M35080 to be recognized. I have both jumpers setup exactly like you did in the video. I can't get the clips to stay on, so I solder the chip to the small boards we get with the programmer. I've tried both 24 and 25 with no success.
I'm a bit lost here with regard to the jumper between 3.3v and 5v. According to the schematic, install the jumper = everything will be 5v? Remove the jumper = everything will be 3.3v?
I bought this exact one when I first started messing with trans temp in circuit programming.
Couldn't find a software for it back then to make it read a eeprom.
I also did the mod from that video and it's still sitting in tool box since then lol.
Bought an AR32 and haven't looked back.
It's a good thing you didn't find software because most of the software before asprogrammer had viruses in it.
@@FixedUntilBroken must have lucked out on that one.
AR32 is a fine unit and that is an even better company. That is my next purchase but the TL866ii plus is doing me very well.
thanks for the video would this work for thee needle sweep on a 2009 mk6 golf gti
Question. I did a swap on my vw. I just want to get the skc code off of the st95040 chip. I don't want the cheapest chip programmer/reader, when I look at Amazon I see all kinds of listings for what appear to be the exact same kinds of programmers under all kinds of different names. Is there a way to know which are genuine and which are knock off? I want a decent setup that will allow me to be able to do effective and reliable chip programming. Any recommendations for brand and type of programmer?
Hello mate, I have a question that you probably will be able to answer.
I’m trying to read a chip that looks like a 93c66w. Actually there is two numbers on it: that one and in the second line it is written 9533w if I’m seen right. So while trying to read it with asprogrammer I have a “check settings” error message while trying to read it as 93c66. I read somewhere that you can read them as a 24xxx or 25xxx chip. What can I possible do?
Reason for it is to recover a lost code from a instrument cluster I have laying around as a learning process
Thank you
You're welcome
To check if the center pins on the 3v3 regulator are common just measure the resistance across them you don’t need to lift the component. I’m sure they are common as this is evident on another video where they are reducing the data lines to 3v3
Help! I just accidentally broke one of the legs in my eeprom do I need to buy one or does it work with solder?
Will this work to clone a eeprom from a Honda? S93C56 chip.
thank you for all the informations. How do we set up 3.3V and how 5V? my jumper is at pin 1 and 2 and i think this is for spi.
My bios chip is mx-12g 25l1605dm2i and it needs 3.3V. I have CH341A black edition like yours. I measured programmer's data pin and i get 5V. i guess this will probably damage my bios chip.
AsProgrammer_1.4.1 doesn't recognize the bios chip.
Any suggestions?
Have you figured it out?
On the back of the programmer where you can solder chips on for programming if you look close enough there is a diagram of the chip printed on the board. The outer one doesn't really say which is pin 1 but the diagram shows you the direction of the chip and if you look at the pads one is different than the rest, safe to assume that one is pin 1. As for the inner one pin one has a circle next to it.
Yeah but the main problem is one is going to be the pin out for spi other is I2c. Doesn't say which is which. Just lazy imo to not mark it in the silk screen but yes it would work. I coated mine in conformal coating though because I'm never going to use it.
@@FixedUntilBroken Very true. Really is no need to use the back especially considering you get a board with it and if you buy it as a kit you get another board already put together.
Hello what about hp bios files .exe it gives 4 .bin files if i choose to make a copy on this pc. which bios file i choose?
Excellent video... I have a GMC Terrain and the radio died. GM designed it such that the deck controls the entire centre console and requires the VIN to match. They want $1000 for a deck and $200 for reprogramming. Will give this a try on a $60 used deck from the wreckers instead.
can this ch 341a read the 93cxx chips ?
Can you please help me to fix my tiger T800 plus full HD receiver flash?
It's not working after take a bad file software by USB.
My regards.
Hi there can you please help me out on programming eeprom 93c46 using that ch341a
Hi sir can I use it also for hard drive bios ? thanks
Anyone know how to read MX25L12833F it doesn’t seem to be supported anywhere
Greetings, the BIOS flasher w/ Test clip to flash BIOS and EEPROM chips is an interesting resolve I being clueless such a fix existed. Considering I've been spending endless hours attempting to normalize my corrupt BIOS that invaded my gravity standing sideways.
I have a dysfunctional Lenovo YOGA 730-15IKB Laptop, question; Are the flasher Test clip Devices universal for all computers or device specific for specific model computers?
Thank you very much for posting a vital answer for this educational post for all of us, remain well in peaceful balance to take good care of it all...
will this write to a 93 micro wire series eeprom as it comes....Thank you
Can we read and program DS 2431 ic using this device??
Trying to read a ATMEL 25020 chip but it not reading, Do you think its bad or do you think I have the setting wrong on my CH341A?
whats the debug saying?
I know this is a fairly old video, and you've posted up the follow up video going over the fatal flaw with this programmer, however, i'm risking it all for the biscuit. lol. i believe i have the hardware setup correctly just by watching this video (when you were setting up your hardware, you did it off screen, so i couldn't really see exactly HOW you set up the hardware), and i've got the clip set on the eeprom without "cross connecting" per your follow up video. the red indicator light illuminates showing the CH341A has power, however when i try to read the chip in AsProgrammer, it says "Error Connecting CH341A (-1)." the "run" indicator light does NOT illuminate at all. Would you say this is a defective unit or do you think i may be doing something wrong? i've been wanting to get trans temp in my avalanche for the better part of about 4 years or so, and i'm finally getting around to actually attempting it. lol. Any help would be greatly appreciated.
Disregard this comment. there ended up being an issue with the driver when I installed in. everything is working and I have successfully programmed my first EEPROM. lol. I appreciate the videos you've done on the trans temp mod. I really appreciate it!
-1 is a driver issue
@@FixedUntilBroken yea, I got it figured out. I actually uninstalled the original drivers from that Chinese website you had and I let windows install the drivers by itself and that’s when it worked. Lol.
@@TheSrT4OwNeR that's funny I had problems with the ones windows installed and had to install it off the website for mine to work. Goes to show how well these things are made lol.
@@FixedUntilBroken yea that’s weird. I guess for anyone who watches this video and reads the comments, let windows try to install the drivers and if that doesn’t work, then use the drivers you mentioned. Either way, I’m glad I got it to work. Btw, what’s the name of your Facebook group? I tried clicking on the Facebook link in your tube but it keeps giving me an error.
Problem not erase spi flash
My problems with this programmer do not erase spi flash can you help me
I modded mine so the interface chip runs on 3.3v for flash computer bios chip because while it has the 3.3v option the data lines are still being pulled to 5v & can fry chips.
Makes sense but that's not what this video is about. It's about programming 5v eeproms in automotive applications and showing that you don't have to cut up the board to do that like the guy showed in his video
Hi man . I have a very important questions for me. Can you answer and help me please ?
I bought this programmer With clip And two " extensions " Blue PCB SOP16/8 And green PCB . Actually i was trying to connect a chip 93c56 from my cluster gauges from Almera N16 1.8 2002 .Once for a few seconds i get chip loaded With As Programming Tool , but connection was lost. My Cliper works really bad , he Is falling down from a chip . Doesnt hold. But sometimes he does. I was able to load a chip for a few seconds through Yellow connectors on the side of programmer. My LED "run" is lighting only when i use a HEAD connection 24 EEPROM , but i have to hold a clip on a chip. On a Yellow connectors no "RUN" led lighting , ONLY red power. But program Is saying that sucesfully loaded a chip.. but Its not loading , after load And changing a clip position Are changing a letters from 00 00 to FF FF FF . SOMETIMES!!! hex text jumps to " ?" Or "#" . Once i had a full Hex text. What am i doing bad ? From your video i got that this programmer can read And edit 93Cxx Microwire chips. Why i can't load a chip ? Thanks man. I Hope u Will answer , because your video Is top about EEproms.
Just pull the chip of the board the clip adapters suck. Use the right sop adapter for your chip instead
Can you show how to program a trans temp on a Silverado cluster with that new eprogrammer please!
Yeah I can show it. What year are you looking for?
@@FixedUntilBroken 03-05 please
Probably be a week or so until I get around to making the video
05-07 classic. Please would be awesome. Gonna do my own soon. Can't wait.
So can this be used to program gm trans temp?
yes
Great video! BTW, the guy on the modification video doesn't know too much about electronics, judging from the meter he uses 😜
I feel attacked by the comment. I have a craftsman Multimeter too. lol. Its not my daily driver but its screen reads better than my fluk does on camera so I use it for videos. My Crasftman multimeter is probably 10 years older than the one he is using though. I bought it back before I knew anything My BK Precision is my bench meter. I think I am going to sell that one soon though and upgrade to a newer one.
How do I do millage correction with this ?
same way as any eeprom based odometer correction. I have other videos on that.
When I listen to you, you seem to be very interested in the same sort of stuff I am, I’d love to pick your brain if you’re interested!
27:13 Use an ohm Ω meter to check the pin-out locations.
Of course you can but the point is they should have just marked the the silk screen it's not that hard to do...
Btw the price of crap burnt up. Probably the 8th time I used it.
@@FixedUntilBroken True, or even mark the pin one location.
I bought a complete set on the cheap off eBay.
@@martyhorten3743 just be careful if you use pogo pins when programming. It has nothing to protect the data lines on the ch341 chip. It the chip didn't like either a dead short to ground on the data pins or unregulated 5volts to them.
There is also no fuse on the usb port so it will try to fry your usb port on the pc when it fails
More views than your video can get eh? I'd say you are pretty damn close! 18236 on 2/13/22 :)
I keep getting error connecting ch341(-1) message I have all the driver's installed
try reinstalling. -1 means it doesn't see it. either a bad usb port, driver isnt working or faulty ch341.
Error connecting CH341(-1) Keep getting this error no matter what I try. Perhaps the driver links don't work with mine.
Maybe, -1 means it's not connecting which is a driver issue
@@FixedUntilBroken Thanks
Great information.
Awesome video.
So, there may be no need disconnecting the 3.3V .
If for any reason you don't want 3.3V at all, it would be best to raise the regulator input leg (5V input); which is the pin closest to R1 as seen at 21:40. If the regulator has no input, then it cannot give output.
On second thought, it's not advisable to bridge the input and output of a regulator and power it up. This could damage it and cause short circuit to your board resulting in reading errors.
You could install a switch to enable you select 3.3V or 5V, depending on the IC you want to program.
You could also raise/disconnect the input pin of the regulator as I stated above.
Dear Bro, you are forgetting that you don't need to pull out EEPROM with clip. It's big plus.
It's also a piece of shit that burnt up because it has no over current protection. And no I didn't forget that I mentioned it a few times
Please i need dump for spi 25x10clnig

I don't do tv repairs. I actually hate working on tvs myself. Indo automotive electronics. Probably best to find a forum that people do that kind of work on.
so your saying all i had to do is use breadboard jumpers on the yellow rail part instead of soldering wires and just use the jumper it came with for 5v wth lol so much easier
Show how to do it instead .
i have done the same just did not think thanks we all miss things.
i just get the error connecting ch341(-1
Driver issue most likely
💯♥️💯♥️💯
lol you need to critique more of these youtube "gurus"
It is fun to do haha. I really need to do a follow-up video on this product. It failed out of the blue and almost burnt up my USB port
No mod needed for 5v, it's for 3.3v (most used in non-automotive chips). The USB outputs only 5v from factory and has to be modified to obtain 3.3v .
Incorrect it is not used at 3.3v in these clusters. yes the ST95020WP is capable of being run at 3.3V but no the 03/04 GM clusters run it at 5V and there is other stuff on that line that runs at 5v. instead of putting a load on that 3.3v regulator I would highly recommend running it at 5v like it is run in the cluster. And no No mod is needed for 3.3V IT HAS A 3.3V REGULATOR ON IT.
this video is about using it in 5v application not 3.3v the point is to show you don't have to cut up the board to use in 5v application. It has nothing to do with 3.3v.
On top of that I need to do a second video on this thing because it's a piece of crap. It let out the magic smoke the first time I miss clipped it. It really needs some level is protection on the data lines plus when the ch341 let's out the magic smoke it wants to take your whole USB port out.
@@user-ic8qh9ot8j I do appreciate you pointing that out though. I was aware it was at 5 volts I show that the ch341 is only getting 5v in the video I didn't really think about that when he was saying that I thought he was saying the 3.3v regulator doesn't exist lol. Point is ch341 is crap spend the extra money get a good eeprom reader. Sometimes being cheap doesn't pay off
@@user-ic8qh9ot8j can't argue their that's true. I just prefer my mini pro if I pull it.
7 minutes in this video and all i've heard is garbage about Chinese labor market and obvious issues with these programmers.
My mama told me if you do not have anything nice to say do not say anything at all. Everyone watching this video knows what you get for 10 bucks.
