The Cambkb is an open-source split keyboard designed by Cosimini. The main objective of the project was to test ideas and get some experience – hence debug pins and empty footprints in the PCB.
Hi everyone, moved to a new city, looking for a new hobby, I found out about building keyboards. […] To waste even more time, I wrote the software by myself, planning to use one of the available ones that many people enjoy using – Cosimini.
Specs
- split, 56 keys (about 6x4 halves)
- Gateron low profile KS-33 switches, hotswap
- Pro Micro controller
- reversible PCB
- RJ-9 connectors
- No OLED screen, LEDs or other shiny stuff
- custom software (Arduino, PlatformIO)
There's a mistake in the RJ-9 connector routing. The author didn't consider that RJ9 cables are typically crimped mirrored, so a custom cable has to be made in order to use the design.
