Overview
Pico keyboard v1 is an open-source printed circuit board by zli117, from the zli117/Pico-Keyboard repository on GitHub, published under the CC-BY-SA-4.0 licence. It is a 2-layer board of 321.8 × 129.3 mm with 160 parts on 106 nets, routed with 559 tracks and 113 vias.
It is built around the RKJXV122400R. Its parts include 68 diodes, 67 switches, 5 resistors, 3 connectors and 2 capacitors. It belongs with the keyboards and input boards and the RP2040 boards of this library.

README.mdPico-Keyboard
A hot-swappable mechanical keyboard built from scratch with Pi Pico board, and 3D printed case, with a very configurable firmware. The firmware is in a separate repo: https://github.com/zli117/PicoMK and can be reused for other RP2040 keyboards.

Overall Cost Breakdown
In total per keyboard material cost is roughly $129.57
- 5 PCB from JLCPCB with shipping: $39.52. Roughly $7.9 per board.
- 100 hot-swappable PCB socket: $14.50. Used 68, so total $9.86.
- Pi Pico: $4.99.
- EC11 Rotary Encoder: $1.10 each.
- COM-09032 Joystick: $4.50 each.
- 100 1N4148 diodes: $4.99. Used 70 so $3.50.
- 150 WS2812B: $14.49. Used 17, so total $1.64.
- 3D printed case. Each part weight about 50g and there are 5 (2 for plate, and 3 for bottom). Total weight 250g roughly $6.
- SSD1306 white color: $3 each.
- GMMK encoder knob: $10.
- Clear joystick knob: $5.
- Stabilizers: $16.99 per set.
- Akko clear translucent keycap: $39.99.
- Akko blue switch: $9.99 per 45. Used 68, so total $15.10
Build Instructions
PCB
PCB is designed with KiCAD 6, and everything is under the PCB folder. Pre-plotted files that can be uploaded to board factory are in
Gerber.zip file. However, different factory may have different plotting settings, so it's recommended to replot with KiCad following factory's instruction. The provided one is for JLCPCB.
Case
Case is designed with Fusion 360. The file ends in .f3z contains the original Fusion 360 source. My build used SUNLU Clear PLA and is sliced with Cura. I put screw holes on the bottom to secure the PCB, but in practice it's not necessary to screw down the PCB once you've installed switches. So those are optional. The screws between plate and bottom are not optional however.
Firmware
Firmware is in a separate repo: PicoMK. Please see the instruction on how to configure and build the firmware there.

Questions
How big is the Pico keyboard v1 PCB?
It measures 321.8 × 129.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pico keyboard v1 use?
160 parts, built around the RKJXV122400R. 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 Pico keyboard v1 KiCad files?
From the zli117/Pico-Keyboard repository on GitHub, at the commit this page was made from: the board is PCB/pico_keyboard_v1.kicad_pcb and its schematic PCB/pico_keyboard_v1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pico keyboard v1 design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
