README
PCB/readme.mdAdalyn PCB
After the development of the handwired Adalyn case, it was clear this great combination needed a formalized pcb. This is that PCB. Designed by tominabox1, the pcb features an ATmega32u4a, USB-C, and ESD protection. The pcb is supported in QMK and VIAL.

Questions
How big is the Adalyn PCB?
It measures 217.7 × 91.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Adalyn use?
76 parts, built around the ATMEGA32U4-AU, PRTR5V0U2X and BAV70. 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 Adalyn KiCad files?
From the Marbelymarble/Adalyn repository on GitHub, at the commit this page was made from: the board is PCB/Adalyn.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Adalyn design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
