An ultra-low profile (Kailh PG1425 "X Switch") keyboard inspired by Le Chiffre.
- 36x 1N4148 diodes, SOD-123
- 36x Kailh PG1425 + caps
- 1x 74HC595D shift register, SOP-16
- 1x Seeed Studio XIAO RP2040
- Solder all surface-mount components on the front of the board (diodes, shift register, XIAO)
- Solder switches
- Flash firmware, install caps, and enjoy :D
Coming soon :D
- "Oeuf Poché" - A 3d-printable minimal case. Mounts with four self-tapping M2x4mm screws.

ZMK firmware available from eggsworks/zmk-config
Gerbers, BOM, and centroid files have been added under le-oeuf/production/. These Gerbers are optimized for production by PCBWay and may not necessarily be accepted by other manufacturers. The BOM and centroid file include only the diodes and the shift register, leaving the switches and MCU to be hand-soldered.
This design is available under the terms of the CERN-OHL-S.
