My macropad with the help from hacklub.com
Macropad is an open-source printed circuit board by RcodePlay, from the RcodePlay/ryanpad repository on GitHub. It is a 2-layer board of 41.5 × 62 mm with 8 parts on 16 nets, routed with 77 tracks and 7 vias.
It is built around the SK6812MINI-E. Its parts include 5 switches, 2 diodes and 1 IC. It belongs with the keyboards and input boards and the RP2040 boards of this library.

It measures 41.5 × 62 mm and has 2 copper layers, 1.6 mm thick.
8 parts, built around the SK6812MINI-E. 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 RcodePlay/ryanpad repository on GitHub, at the commit this page was made from: the board is PCB/macropad.kicad_pcb and its schematic PCB/OPL_Kicad_Library-master/OPL_Kicad_Library-master/Grove Vision AI V2 Library/Grove - Vision AI Module V2.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 RcodePlay before reusing the design.
