The 78 most common of 80 parts.
It measures 36.4 × 55.2 mm and has 4 copper layers, 1.6 mm thick.
80 parts, built around the TJA1443AT/0Z, PESD2CANFD24L-U, MBR130T1G and SP0503BAHTG. 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.
From the leonrinkel/sam-fd repository on GitHub, at the commit this page was made from: the board is rev1/sam-fd-rounded.kicad_pcb and its schematic rev1/can.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask leonrinkel before reusing the design.

Arwinplayz/Split-Keyboard-V2
I decided to make a V2 which would allow me to redo/refine some features. That is I want to add a LiPo battery and change the requirement of having both sides plugged in separately to the PC.
