Overview
0xLM is an open-source printed circuit board by llmerlos, from the llmerlos/0xLM repository on GitHub, published under the CERN-OHL-P-2.0 licence. It is a 2-layer board of 283 × 100 mm with 100 parts on 125 nets, routed with 597 tracks and 53 vias.
It is built around the CH559L, USBLC6-2SC6 and CPG135001S30, with the TS-1187A-B-A-B, TYPE-C-31-M-14 and PMEG2010EA among its other parts. Its parts include 46 switches, 8 resistors, 6 ICs, 4 capacitors and 4 connectors. It belongs with the keyboards and input boards and the 8051 (CH55x, STC, AT89) boards of this library.

3x6 + 3 Split Ortholinear Keyboard with on board MCU
Why?
I wanted to make a compact keyboard by using the minimum surface for the keys with all the components underneath them while no increasing the height of the overall keyboard.
Characteristics:
- CH559L FAK powered.
- Direct pin with ESD and over-current protection [Schematic].
- 3D Printed Case.
- PCBA ready* (See Known Issues).
- Choc V1 spacing.
Pics
Known Issues:
- USB part is a little bit missplaced and requires triming the legs (for a fee in JLCPCB).
- USB part is for 0.8mm PCB instead of 1.6mm PCB.
- BOOT silkscreen rotated 180 degrees on the right PCB.

Questions
How big is the 0xLM PCB?
It measures 283 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 0xLM use?
100 parts, built around the CH559L, USBLC6-2SC6, CPG135001S30 and TS-1187A-B-A-B. 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 0xLM KiCad files?
From the llmerlos/0xLM repository on GitHub, at the commit this page was made from: the board is PCB/0xLM.kicad_pcb and its schematic PCB/0xLM.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 0xLM design in my own project?
Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
