I've been working on this design for a while and I thought you guys might be interested. It's still in the prototyping stage, but it should be usable fairly soon.
I just got the pcbs and I'll be working on a port of tmk firmware to nrf52 based keyboards.
What do you all think about this design?
Notable features:
- Single controller (using nrf52832) to enable longer battery life
- Compatibility with many 60% cases (anything a gh60 would fit in)
- Multi protocol support planned
- logitech unifying
- hopefully usb (by bit-banging 1.1 low speed)
- OTA firmware upgrades planned
Potential features I might look into:
- RGB backlight
- layout improvements?
