The default on esp32-s3 is Gpio8 & Gpio9, but you can assign them to whatever pins that are free on the ESP32 based boards (GPIO8 to GPIO14 seem to be good targets?) just assign the correct pin numbers using the function: Wire.begin(sda, scl); in your code.

@@Tech-Relief thank you very much.

Got them from Shure tech support, they were only $1.80 each.

Not sure what you are asking, you mean can it be used as a frequency counter?

I don't know,why I'm interested this model haha. I'm already buy 1.dso138 2.gm328 3.lcr t7 4.tester counter crystal oscillator

Sure but just sometimes there is very little room and then a pair of hot tweezers are indispensable.

Well the idea is that the current capability is so low that any resistance will lower the voltage to where some current will flow. i.e. the output impedance is very high. Most modern components will then show the voltage at which they are starting to break down. Having said that, it is true that old capacitors may break down and be damaged before the voltage is reduced. I have seen this on 60 year old paper capacitors. So this device should be used with caution.

Better than crap music!

If you are talking about the microscope camera, it does not have autofocus so I assume you mean the auto exposure? In that case yes I use it with auto exposure turned off so I can adjust the external lighting to get the best exposure.

I tend to use the .5 or .75 barlow les as appropriate.

No the RGB Led came with the board and the code was simply based on the Arduino RGB Led test code available in the Arduino IDE samples.

@@Tech-Relief thanks I found it under esp32 gpio I realize some boards esp32s3 works but not this version as there is an area RGB soldering split into half. I read other comments that need to soldered together then it will work, have U try RGB and work out of the box?

@@yes_man_lol Yes the board I have did not need any links to be soldered. As far as I remember it just worked.

Have a look at the Tech-Relief Github repositories: github.com/TechRelief?tab=repositories

@@Tech-Relief I have checked it but didn't find these codes. It will be helpful if you publish this as well.

@@Tech-Relief It's not there

@@LearnTodayTech Keep in mind this code was used as a way to test keyboard output using the Seeed Studio USB OTG Board which has an LCD display. Is was meant to be a step moving toward software leading to the USB KB Input and BLT Output. However, I pasted the code here which has evolved a little from the one in the video: pastebin.com/yr5FVK9P That is about all I can do right now...

@@Tech-Relief Thank you so much. Let me try this.

just go with ESP32S3 Dev Module

So I use PlatformIO with VS Code instead of the Arduino IDE and there it is known as: esp32-s3-yd-wroom, I would try some of the other ESP32-S3 boards listed in the Arduino Board manager with similar characteristics. Or better still just migrate to PlatformIO ...

@@Tech-Relief Hi ! So for some reason the borad "esp32-s3-yd-wroom" is not showing in the board section of platformIO, why could this be happening?

@@MarEz1309 Not sure make sure you have the latest updates for platformio. However, you can download the .JSON board file from this location (save it as esp-s3-yd-wroom.json): pastebin.com/UcxDxmfk Save it in the platformio boards folder: C:\Users\{your-user-id}\.platformio\platforms\espressif32\boards Replace {your-user-id} with your actual windows user id, it should then show up when selecting boards... Hope that helps?

Yes, these are the hot tweezers I use. They are very good.

Not entirely sure what you are talking about. I used that board on purpose it is a board that was coated with something to seal it and was designed to go up with a weather balloon at very high altitude and it is difficult to remove components from it. Using cheap hot tweezers did not work on this board as a previous video showed. The Atten tweezers made it possible to remove the components and I use them all the time, on a standard PCB the components come off with or without flux immediately. They can be used in cramped sections of a PCB which you could not do with two soldering irons. I mean there are many ways to desolder components and you can use the method you like best for me I use the hot tweezers often and they work well for me.

@@Tech-Relief oh I didn’t realise it was covered in a conformal coating. Because RUclips is playing up, I don’t watch in HD anymore. So everything is blurry.

@@Tech-Relief have you tried using a regular soldering iron with a tip that can touch both sides of a SMD capacitor at once? The common Chinese knife tips can do it, but I’ve seen better geometries specifically designed for the job.

I am not sure if it remembers all of the settings but it seems to remember the current setting and the limits for Amps, Watts and Voltage and the settings I changed originally.

Yes, I am. mostly doing this for the challenge and some fun.😊 you are right there are a number of ways to deal with the lack of plated through holes. I could have just put on some large vias and simply soldered a piece of wire through them but I was wondering if I could use copper foil... I use this foil for fixing broken tracks on pcbs as well.

With regard to the battery capability it is able to run from a li-ion battery and also charge it. However, I had a circuit in which I connected an external device to the 5V pin but it did not work well (perhaps it drew too much current?). I chose to use one of those li-ion cell charge / boost boards externally and not use the battery capability of the microcontroller board in that case. Secondly, the USB-C port can be used in host mode but then (since there is only one port, the pads on the bottom connect to the same pins as the USB-C socket) you will have to hold down the boot button to put it back into serial mode for uploading code.

It might be useful for some people but a separate multimeter and thermal camera is much better...

@@Tech-Relief I got an Aneng multimeter 8009 for 15 euro delivered and it's a brilliant machine. I personally cannot see how combining a thermal camera with a multimeter would be of any benefit.

@@Tech-Relief If Aneng make a thermal camera, I will snap it up.

Yeah, I hate background music also'''

I am completing several projects right now, and I will have a look at it when they are done. However, what are you connecting to the board?

@@Tech-Relief I was trying to connect a temperature and humidity sensor, Adafruit AM2320. I ended up purchasing another one DHT22(that does not require I2C protocol, and it worked perfectly). Today, I wanted to try creating a circuit using the 5Vin pin, and I find that it does not work automatically like 3V3 pins, and I have no idea how to make it work. Do you have any recommendations fro that?

@@emrebaser3803 I am out of town right now when I get back next week I will have a look at it.

@@Tech-Relief I have a proyect on ESP32 (pin 21 for SDA and pin 20 for SCL.) with a RTC that im going to export to S3 and the fist think that i check was the pin out for a esp32s3, and thearent the same, check the S3 PIN OUT AND LOOK for SCL 9 AND SDA 8 on s3 not all PINOUTS FOR S3 HAVE LABLED SCL AND SDA

@@emrebaser3803 solder the in out pad on the board and the 5v pin will work fine

Yes it is possible to send key combinations. Some keys like shift, alt, ctrl and the windows key are treated as shift keys and these will appear in each data packet as long as they are held down.

Yes as far as I remember the hid codes between USB and Bluetooth are identical.

I am not sure what type of sensor is used but the standby and wake up time is programmable and works perfectly for me.

@@Tech-Relief thanks for the answer :)
