Overview
Pcb-40 is an open-source printed circuit board by dcpedit, from the dcpedit/tklish repository on GitHub, published under the CC-BY-4.0 licence. It is a 2-layer board of 309.6 × 100 mm with 161 parts on 109 nets, routed with 1,391 tracks and 101 vias.
Its parts include 65 diodes, 9 capacitors, 3 resistors, 2 ICs and 2 switches. It belongs with the STM32 boards of this library.
README
README.mdTKLish
TKLish is a series of PCBS that mimic the style of a traditional TLK (Ten Key Less) keyboard. Below are the 3 variants:
- s40 - 40% layout with staggered keys. KLE layouts
- o40 - 40% layout with ortholinear keys. KLE layouts
- o80 - 80% layout with ortholinear keys. KLE layouts
Features:
- s40 can use standard keycaps (no 40s kit required)
- s40 & o80 can utilize any ergo/ergodox kit with 1.5u modifier keys (ex. GMK Sixes, SA Carbon)
- PCB can support up to 3 rotary encoders
- Utilizes Unified Daughterboard (C4 version with Molex Pico-EZmate connectors)
The o80 PCB should work with any case that does require the PCB to be mounted (PCB has no mounting holes) and utilizes a USB-C daughterboard. I've only been able to test it with the Thecca x Rubrehose case.
Stacked Acrylic Case
I've designed a stacked acrylic case that works with the 40% PCBs. You can look at the build guide in the case directory.

Questions
How big is the Pcb-40 PCB?
It measures 309.6 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pcb-40 use?
161 parts. 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 Pcb-40 KiCad files?
From the dcpedit/tklish repository on GitHub, at the commit this page was made from: the board is pcb-40/pcb-40.kicad_pcb and its schematic pcb-040/Matrix.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pcb-40 design in my own project?
Its repository publishes it under the CC-BY-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).
