I was able to source a full BOM. Some parts had to be substituted as the originals are hard to source using traditional suppliers. This BOM can be found in my PCBWay community page linked in the description!
Ah, had to go back and verify: 2:41 you added the two 5.1K pull down resistors on cc1 and cc2 so it will charge from a USB-C source. Good job! Also, awesome rework, the true spirit of the maker/engineer: "This is not right, I will modify it to be correct"
Thank you! :)
That is such a sick modification 👏🏼. I'm always baffled when I see new devices these days that still have Micro USB over USB-C, so it's nice seeing that they could be changed over.
I would honestly love to hear the reasoning behind such a barbaric choice lol
@@Solder_king Isn't it obvious? $$$
@@Solder_king It's because they haven't redesigned it since it's release in October 2017, when USB-C existed, but was very rare
I use small magnetic charging cable adapters on devices like this.
Solves the problem of looking for specific cables.
Such a fantastic upgrade, I've been dreaming of this for a while now, it is my last item without USB-C... Hope you get a full bom sooner or later. Thank you for your work.
Have a full BOM order coming in two days! If it all works as I had to sub parts then it'll be released shortly after :)
Great work~ I didn't expect a seemingly simple modification to be so involved
After I took apart the mouse I almost put it back together and shelved the idea 😂. I originally was hoping to just use a breakout PCB.
@Solder_king I may have missed it but are you planning to sell the boards populated with components?
With regard to the sponsor, yes you could have had it sponsored either way you said as much, but from PCB ways perspective I'm fairly certain that a video that contains an example of the product I manufacture showcasing the quality would be much better than a video where the person is just telling the customer about it as physical items speak to their quality better then just vocally saying it.
@@reverberer I'm not selling anything. I'm going to provide a product link with a full BOM. The PCB can already be purchased through PCBWAY as a transplant board but the goal is to get a full BOM so anyone can buy a fully assembled one if they want.
That's how sponsors work. Even if PCBWAY wasn't sponsoring me I would've had this PCB made as I've done in the past. Saying I'm doing it just to thrown out sponsored content is just wrong.
@@Solder_king Fair enough, then although I won't use it as I don't have the actual mouse or the skills to do all the soldering required to make the mod board for you for your time and effort designing the board, as designing custom PCBS is definitely not approachable for your average novice or beginner like me.
Also eventually if some one were to construct the boards once a full BOM is established and then sell them that would be great as well as I know for a fact soldering / desoldering some of the components such as the ribbon connector isn't very approachable for a beginner / novice with my skills below. There are a lot of people like myself who admire your skils certainly with the ability you have shown with the reading of the circuit, design of the PCB, and identification and sourcing of the components, which is why I assumed you could have found a USB C connector that could have fit. I especially wish I could get my head around circuit design, but I suck at it which Is why I leave it to professionals such as yourself. For a novice like me, the two most approachable solutions are to either use a pre manufactured purchased board, or as I did with my torch, replace the connector and just make it work.
Just quoted 5 assembled boards on PCBWay. Cannot wait to have them. Sir, you are a boon to humanity!!!
Very awesome video. The outdated usb has been my biggest gripe with one of my very favorite mice
to a lot of people might feel like "why not just buy a new one"....but seriously i RESPECT you for going through all this to make it yours and make it fit your needs by yourself....absolutely love it....and got a huge SUB from me.
well...the answer is - because this is the new one. It should've been designed with usb-c
100% agreed, especially from Logitech..they've been around forever, they can't be pinching pennies when they sell that mouse for that price...kudos to you for making this video...hope they see it.@@dimitrijekrstic7567
Logitech does sell trackballs that charge using USB-C - however: They don't sell one with this model's capabilities, which can be paired with up to two devices (your choice of using the Logitech dongle or Bluetooth with one or both devices), plus other advantages over their cheaper trackballs. Truthfully, they should release a successor of this model. One that you can use with up to three devices, like all their wireless keyboards these days, but other than the Micro-USB/USB-C issue, the existing MX Ergo trackball probably needs to be around for three more years (10 years total) before they would consider completely supplanting it.
When I bought mine, I was most suspicious of the rechargeable nature of it and thought the battery would die within years, like a smartphone's can, and Logitech even planned on offering replacement batteries, but that idea disappeared quickly, although you can get replacement batteries off of eBay. Seven years later, that trackball battery still lasts me months, I have a second trackball I keep in the living room, and my wife uses one, too. Oh, I bought my step-nephew one as well when his old battery wireless Logitech trackball died.
Long digression, but also when I bought my first MX Ergo (Plus) in 2017, my Pixel 1 was the only USB-C device I owned, my tablet was still Micro-USB, although I was already sold on the idea of USB-C being used for everything.
Great video shows how clean this can be done. I did a similar USB C transplant onto a MX Master from 2016 but much less refined just slapped a aliexpress USB C 5V breakout board inside fixed the port with solder to the ground plane and it still works. Only issue is the soft rubber shell degraded over time and I had to fix it with some sugru too.
Wow! Great mod. I would have never thought of doing a transplant PCB. I would have wasted way too much time and money buying the exact components.
Damn you really are the solder king
Absolutely beautiful job.
@SolderKing that is a freakin good mod you did there! I just wanted to find a video of someone replacing the battery as mine is dead but this has me inspired to upgrade the board to C too!
The switch replacement was also hecking helpful. I'll need to disassemble my brother's mouse and fix his switches too
thanks!
That's a dope mod, if they don't do it.. you do it yourself. Love it :D Next time please show us the sweet satisfaction moment, when you plug in the usb-c during a closeup and show how the light turns on!
I totally should have shown it plugged in all together at the end 😅
This is really frikkin cool
This reminds me I need to go back to my old mouse and finish USB-A to C conversion I started last year to ditch my dongle for the 2.4hz receiver of the mouse.
i got a logi mx master 2s and was surprised it used a micro usb for charging and yes, i had to go fetch for one even though it does come with one for charging lol i might try doing same thing. thanks for this
My guess why logitech still uses micro usb is that it sells too few to warrant a PCB/ injection mold redesign, or even depending on production process, they could still be using shells/pcbs made years ago.
That would make sense! I wondered if they perhaps use the same board over a few products and just had a stockpile to burn through
man, Track ball mouse used to be so simple. They used to be just a PCB and some rollers with sensors to detect the movement of the track ball. I still remember that time at school when the balls on our mouse were stolen by other students so we had to improvise by reaching into the mouse through the hole for the track ball and manually turning the rollers inside to move around the cursor on our screen. It was really hard but looking back it was a really enjoyable experience. I actually wish I can find an actual track ball mouse from the early 2000s to displace on my desk or heck even try gaming on one.
you really are solder king :joy:
Man, my MX Ergo switch just gave up and while looking for some video on how to replace them I stumble upon this video. I'm not sure I have the guts to enterprise this but if I do I might order the fully assembled PCB from PCB way and do the case mod at the same time.
10 out of the 10.
I have one of these, and yeah the micro USB is crap.
As for the switches, I had the plastic that presses on the switch wear out before the actual switches. I was all ready to start soldering and instead I had to epoxy the bottom of the buttons to rebuild the material to press the switch down again
my favorite mouse from logitech is the MX510 and it uses batteries, barely ahve to replace em. like once every 6-8 months
Nice mod however the rubber coating on the shell would break down long before the micro-usb port would...I bought my third MX Ergo few month ago.
This is why I stopped buying them. After my second one, I just got tired of the unpleasant feeling of the rubber when it starts to wear.
want to donate one? I would love to see if I could do something about the rubber
@@Solder_king If you are in the UK I am more than happy to do that!
For this exact reason I went with ProArc EM01. Which seems very similar to this Logitech mouse, but its cheaper and has USB-C.
Since I do believe the Ergo is overpriced, I started reading up on the EM01. Looks nice, I wonder how real those dpi settings are, if not faked they are a huge bonus over the Ergo, somebody also mentioned the ball stay smooth (although they probably meant the 'bearings'). However, while I lament the lack of USB-C on the Ergo, can you please test / confirm for me, can you use the EM01 while charging?
@@Windgazer42 You can charge the EM01 and use it (connected via Bluetooth tested).
How might one modify the MX Ergo to be fully wired (no battery or bluetooth)? Could this be done without replacing the stock PCB?
What I actually bought for my mouse and another tools with rechargeable is got a magnetic charging cable with all 3 possible ports and it basically makes all into 1 cable. Saves the headache right?
You have missed an amazing opportunity to put Cherry MX Ergos inside an MX Ergo... I guess you could still do it
Do you have a part number for the mucroswitches?
Mine's going to get this treatment soon enough too
personally I would just preorder a gameball thumb and use that.
at least the gameball thumb uses a proper sensor, has USB C, and fully wired connection. plus it's the same price or cheaper than the logitech.
I love this mouse, even with this old usb hehe, but it would be a 10/10 if i could change to silent switches easily 😢
How much Space is in the Shell?
The Battery looks very small in Comparison.
I'm conflicted on this mod. on one hand I have HATED micro USB since they replaced USB mini with it, and on the other hand, as you said I only have to charge it about 3 times a year.
hunting down a micro USB isn't an issue for me since I have a couple old USB batteries and a couple PS4 controllers that use micro USB that are floating around. so long as they don't all go flat at the same time I have a dedicated Micro for charging at my desk
@Solderking, Any chance you have the details of FB1? due to a faulty cable FB1 burnt on my MX ergo.
That is honest surprising since it's basically doing nothing. I'd love to see some pictures if you have them.
I am compiling a BOM and have the first kit testing now :)
Did I just saw this schematic on reddit?!
Possibly :)
I need this for mine where can I download this and get it made so I can try this mod
7:30 you were not talking too much.
What was the switch on the PCB for? Was it the original mouse switch or a new component? It was a but unclear when you were installing it.
The switch was apart of the original board. It functioned as the on/off switch for the mouse. I happened to find a replacement one online and used it instead of picking the old one off the original PCB. I did that also with the connector. The reason behind that was to provide a substitute part if they were damaged during removal :)
Huh, didn't expect it to still use micro USB. I bought mine when that was still somewhat reasonable, but I expected them to have moved on to USB C long ago.
Wait why can't you tell the name of the mouse switches?
Because I have no idea how to pronounce them 🤣
They're YIMAGUJRX Kailh GM8.0 :)
@@Solder_king oh xD
Would it have been possible to just replace the USB port on the existing board?
Technically yes but the pin out would not have matched, and you'd have to add two resistors to the port. It would end up being a lil wire ratsnest.
I’d buy this. Thrifted one of these mice for $3 and micro-USB is a bummer
What's the name of the switches?
I would also like to know which switches were used as a replacement. Great build and thank you. The switch definitely fails after a little over 1.5 years of daily use. Seems to always happen in the middle of a project so I have few to repair/upgrade.
Whats the name of the switch?
Fun little mod. Hope its not necessary in the future thanks to the EU small electronics bill.
I just bought a new Zoom H1 (the 2023 version) and was so mad it didn’t have usb c yet.
What switches did you use?
YIMAGUJRX Kailh GM8.0 :)
@@Solder_kingha just commented for these. Great build.
Meanwhile me: sending back my razer naga for warranty repairs every year for past 4 years, and hoping they will give me new version with usb-c one day
7:15 Kailh? Kauhia?
The micro usb on this mouse is a pain. I never get it right the first time as it's weirdly positioned on the mouse and well.. it's keyed :/ I really wish this was the standard model and I'm not even that big of a usb-c fan, that's how annoying it is.
It is rather ironic. Even the new version still has micro while the ergo keyboard for the set has usbc. But what really annoys me is that they make a non trackball version that has additional scroll features but refuse to add the support to this model.
you know they make usb-c ports with micro usb pinouts for this exact purpose right? they have 5 and 2 pin variants.
And I made this for ease of ordering and for others who don't want to/know how to solder.
Im sure you could make some money from either:
1. Selling the PCB with all the parts in it as a drop in replacent, only needing the customer to shave away some plastic for the larger USB C commector
2. Selling a couple of these to people who really want a USB C version of the ergo
This is definitely a niche, it just depends on what people are willing to pay for this upgrade. Pro tip, even though people say they will buy something that does not mean they will buy it. Trap I fell into. Start small and let the sales figures do the talking :D
I wish I had the time to do this mod, I use an ergo m575 but ive been wanting to upgrade to the newer MX ergo lineup. You possess some very good skills, you will go far
I use this trackball all the time as my main mouse. Wish it had a usb c. No way could i do this mod myself.
If you could live without it for about a week let me know :)
I know pcbway is a sponsor and the video would have been pointless, but did you try to find a usbc-connector with matching pinout to just unsolder the connector and add the usb-c
I would've done this without a sponsor like I have in the past with other videos.
You can't find a USB C drop in replacement due to pinout and needing two additional parts.
:( Way too expensive, for me, unfortunately. It looks like it's reasonably priced to get them to assemble it for you, but once it goes through their process, it comes back at twice the total price of what it initially showed you. Oh well, very cool anyway, and I wish I had the patience to assemble it myself. Maybe 30 years ago, but I don't have time now. At least the Micro-USB ports on my wife's and my own three MX Ergo haven't gotten loose like some old phones.
I would just buy an adapter (c to micro)
I can't live my life using dongles lol
micro usb? Just why?
Why do so many companies choose that port? Are their products in development for like 10 years?
Did you say 800$ !???
Are you seling ?
I have one left :)
@@Solder_king perfect
mind giving it to me ?
@@user-bc3cn9kl3k asking 15 per board
i was asking more of the mouse not the board
@@user-bc3cn9kl3k sell a modded mouse or mod your mouse? If I were to mod yours it'll probably be around 40 and if I were to sell a modded one it'll be probably around 140.
no one makes a drop-in usb-c port component with the same footprint of a micro port yet?
Probably not. And if they do that doesn't include the two 5.1ks
As per USB standard, micro USB still make sense for devices like mouse because USB-C is initially designed for dual-role things like smartphone
I just bought a magnetic charging cable set for mine... much cheaper.
If it works for you that's all that matters. I like a more concrete solution that doesn't involve dongles or adapters. Plus for me the process is a lot of fun.
Micro USB is a cancer we can't seem to cure.
Dont understand why is this a wireless mouse just use a fucking cable.
It's also Bluetooth so using it with my laptop without needing a cable is a plus.
Wow that thing isn't worth 100$.
Using a trackball is weird - I don't get it. The fact that you are worried about the port that a device which doesn't even move uses is also confusing to me. HOWEVER, I admire your passion, and while your end goal is questionable to me, you crushed it in execution. Great work.
Logitech is bad and they should feel bad.
