Hi guys
I want to design a wireless macropad. With battery, and bluetooth module (nordic semicon nRF module I think).
I have experience with 32u4s, DFU, QMK, and circuit design.
I'm missing details on:
* Which nRF module to use? (best?)
* Circuit for safe battery management (lipo)
* KB firmware for nRF module (obviously it's not going to run QMK, and I don't want to reinvent the wheel)
* How to flash the nRF modules? Do I need one of their devkits?
There are open source keyboard designs out there, making use of some (all) of these elements...
I would like to study some of these designs to learn how to make my own.
Where is a good starting point? Any open source boards which you think are worth a look?
Are there any tutorials out there that might be relevant?
Thank you sincerely
