macropad but cybdo!
CybdoPad is an open-source printed circuit board by Cybdo, from the Cybdo/CybdoPad repository on GitHub. It is a 2-layer board of 102.3 × 72.6 mm with 43 parts on 54 nets, routed with 254 tracks and 0 vias.
Its parts include 24 diodes, 13 switches, 4 resistors and 1 connector. It belongs with the keyboards and input boards and the RP2040 boards of this library.
A Pi Pico powered Macropad!

I needed a macropad, and my hackpad is long overdue. Might as well finish it now!

It measures 102.3 × 72.6 mm and has 2 copper layers, 1.6 mm thick.
43 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.
From the Cybdo/CybdoPad repository on GitHub, at the commit this page was made from: the board is PCB/CybdoPad.kicad_pcb and its schematic PCB/CybdoPad.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 Cybdo before reusing the design.
