overview

bykeeb stands for "Baby Yoda Keyboard"

This is a 36 key wireless keyboard using a seeed xiao nrf52840 controller, supporting choc, gateron low profile, and MX switches.

key features

  • 36 keys
  • seeed xiao nrf52840 controller
  • hotswap or direct solder support for choc, gateron low profile, and MX switches
  • battery cutout in pcb for a 32mm x 20mm x 6mm battery
  • battery through holes for soldering a JST connector or direct wire
  • on/off switch
  • reset switch

important notes

  • This keyboard is wireless only. You cannot use a xiao rp2040.
  • The switch spacing on this board is what I call min-y standard-x spacing. This is 19mm x 16mm. In the pictures above, I'm using CMY keycaps.

firmware

Firmware is done in ZMK, and can be found in the zmk-fingerpunch-keyboards github repository, specifically in the boards/shields/bykeeb directory.

Questions

How big is the Bykeeb PCB?

It measures 246.5 × 92.8 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Bykeeb use?

93 parts, built around the 1N4148W. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Bykeeb KiCad files?

From the sadekbaroudi/bykeeb repository on GitHub, at the commit this page was made from: the board is pcb/mx-choc-ks27/bykeeb.kicad_pcb and its schematic pcb/mx-choc-ks27/bykeeb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Bykeeb design in my own project?

Its repository states no licence, so its author keeps all rights: ask sadekbaroudi before reusing the design.
