Overview
Adelheid is an open-source printed circuit board by dcpedit, from the dcpedit/adelheid-plus repository on GitHub, published under the MIT licence. It is a 2-layer board of 339.1 × 143.2 mm with 332 parts on 228 nets, routed with 3,226 tracks and 99 vias.
It is built around the ATMEGA32U4-MU, USBLC6-2SC6 and PF4. Its parts include 83 diodes, 13 connectors, 9 capacitors, 5 resistors and 2 ICs. It belongs with the AVR (ATmega, ATtiny) boards of this library.

I modifed the pcb a bit to accept an Atmega32u4-MU since those seem to be in stock more often.
Changes in this fork
- USB-C connector
- Option for 2U backspace
- Extra
Bkey - Option for rotary encoder at
F13position - Option for 2.25U left space + 1.25U modifier combo (requires modification to plate)
Layout
Firmware
See my Vial fork for the firmware files on the dcpedit branch. I opted for Vial since it allows you to program the rotary encoder through their GUI: https://get.vial.today/

Questions
How big is the Adelheid PCB?
It measures 339.1 × 143.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Adelheid use?
332 parts, built around the ATMEGA32U4-MU, USBLC6-2SC6 and PF4. 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 Adelheid KiCad files?
From the dcpedit/adelheid-plus repository on GitHub, at the commit this page was made from: the board is pcb-mu/adelheid.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Adelheid design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
