A 75% mechanical keyboard that uses a Xiao RP2040, Choc switches, and I/O expanders.
The design of this keyboard should work, but I have not yet received the PCBs and tested them.
3 PCA9505DGG ~6$ 1 Xiao RP2040 ~5$ One custom PCB ~20$ Kailh Choc switches (84 pcs) ~40$ Kailh Choc hot-swap sockets (84 pcs) ~10$
The goal of this project was mainly to build a keyboard to my liking. None of the keyboards I found were exactly what I needed, so I thought, "Why not build my own?" I have been meaning to learn KiCad and Fusion 360. My currwnet kyebord is one of the old apple usb keyboars, ideal,
so far I mesed up the pcb so I have to make a PCA9505DGG Interposer so I can rwriew the trases
My requirements were:
- Choc switches
- Hot-swappable
- Easy to solder
- Uses QMK
- has audio swithes
- gerbers scroller7.kicad_pcb.zip
- kicad files scroller7.zip
case is pretty basic and will be changed it is split so it will be printed
