Overview
Keyboard is an open-source printed circuit board by 1215-tech, from the 1215-tech/WD66 repository on GitHub. It is a 2-layer board of 314.3 × 95.3 mm with 167 parts on 106 nets, routed with 848 tracks and 74 vias.
It is built around the ATMEGA32U4-AU and SRV05-4. Its parts include 68 diodes, 7 capacitors, 4 resistors, 2 ICs and 1 connector. It belongs with the keyboards and input boards and the AVR (ATmega, ATtiny) boards of this library.

As of 12/21/2023 PCB is finished and tested
As of 12/01/2025 the project is archived, we are currently in early stages of developing the HE version of WD66
As of 17/09/2026 firmware and hardware have been separated into different repos
Witch Doctor 66 is a 65% mechanical keyboard, with layout similar to Leopold FC660M. The idea is to make it compatible with Leopold's case if you don't solder in 2 switches. You can find pictures of implemented layouts and layouts planed below, as well as pictures of the PCB

You are welcome to fork, modify and produce it on your own, that said I would like to be in the know about production for profit, work email is readily available on my github profile; also don't be an ass, don't erase the solder mask art
Huge thanks to my friends FOXY and ANV3R for supporting me through this project

Questions
How big is the Keyboard PCB?
It measures 314.3 × 95.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keyboard use?
167 parts, built around the ATMEGA32U4-AU and SRV05-4. 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 Keyboard KiCad files?
From the 1215-tech/WD66 repository on GitHub, at the commit this page was made from: the board is PCB/keyboard.kicad_pcb and its schematic PCB/keyboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keyboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask 1215-tech before reusing the design.
