nrfmicro VS redox-keyboard

Either way, my advice is the same, first checkout this document which has known issues for a bunch of controller alternatives. Next, I'd recommend asking on the zmk discord since the zmk developers hang out there and are pretty active and helpful.

I'd give this a read. Should tell you everything you need to know.

Thank you! I have already connected the nrfmicro wireless controller to this board. It worked great!

Or this one https://github.com/joric/nrfmicro I made it to my board and works perfectly and it’s relatively easy to build even with just solder iron.

the nrf micro project is open source so you can review the schematic as a starting point https://github.com/joric/nrfmicro

If you can find nrf52 modules where you are then that's a good start, if you're not too scared of DIY intricate soldering then you can use them to build your own NRF micros. Ultimately the controller on these modules is the same as that of a nice!nano and if thus capable of running ZMK alone, there's not really a way as far as I know to pair them with a promicro or blackpill or similar to get a fully wireless solution.

slightly modified nRFMicro 1.4

Nothing I could say will be more thorough than this.

Use 3 of those YJ-14015 modules (e.g. https://github.com/mattdibi/redox-keyboard/tree/master/redox-w) with a Pro Micro Q2: Is there a way to generate the PCB for this with ergogen or do I have to wing it in KiCad?

After some initial research, I've found a couple of models that seem to meet my requirements: the Lily58 and Redox-w v2.

There's a website that has a bunch of split keyboard layouts you can print out at full scale and sort of test drive really easily. I did that and found I didn't like the moonlander or ergodox thumb clusters, which is why I went with a Redox instead.

It's just a remix of the original case. Mattdibi also included the STEP and fusion360 file. What I changed on that case: Add a cavity for a 503035 battery, Add a ~3 degrees tilt for the battery and Hex insert for the nuts, making it much easier to assemble / disassemble.

If you want more of a full-size, five-row configuration, get a Redox PCB from Falbatech or Beekeeb.

To anyone who is here in 2 years looking to find a good case the soldered PCB is listed on the official GitHub ( https://github.com/mattdibi/redox-keyboard) as the Redox rev1. 0W. This is the soldered version and is the exact same as the one sold on falba tech and is compatible with the official case found here: https://github.com/Pastitas/Redox-neodox-Case.
