Soldering Tips / Suggestions - Reversible PCB about ergomax HOT 7 OPEN

You will need to solder a wire between the ground pin of the microcontroller (on the left hand board, that is the second from the top right) and the ground pin of the TRRS jack (it is the pin apart from the column of three) if you want the boards to work together over a TRRS cable.

Oh thank you very much @LouWii!
Somehow I missed the notification here. I started right side for now following the images of completed builds, haven't completed yet though.

I'll get in touch with you via email by end of the week and plan something.

@BenMMcLean thank you for the tip. Definitely helpful. Will do it towards the end of the build.

I just finished a build of the reversible PCB and can confirm the reversible PCB works fine with a TRRS cable.

There's nothing too tricky – just pay attention to which side of the board you need to solder the components to, as shown in the photos. There's no need for a wire anymore.

Hey,

I haven't got the reversible PCBs built, so I can't really help right now. I made it as an experiment, but it might work. I'm willing to buy a PCB set off you and have a go at it if you want. I can even come pick it up in person. I can bring you a set of the left + right PCBs, I have a few left that I never used.

Can you share how the build went? I also ordered a Reversible PCB, and I wonder if it is possible to build with this.

I have the right side ready (except the case and the firmware) and as @sohocoke said, the process is straightforward.

I took my time to understand the correct sides from the pictures on the repo, even though those were of the non-reversible pcb, and it helped.

In my case, since I got the prints before the trrs fix, I'll need to add the ground wire.

As the repo does not have the kb-layout file for the right side, I compiled the left side and flashed on the right just to check the key presses. Still have to find time to learn and create one.

If you need some particular details, I am willing help with best of my knowledge upto this point. This is my first keyboard build experience so you may need to double check with the info I'd share.
