FirmWare
right now, the firmware is just a numberpad, but when I assemble My macropad I'm going to set it to random miscellaneous shortcuts.

Questions
How big is the RAM PCB?
It measures 126 × 109.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RAM use?
34 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.
Where can I download the RAM KiCad files?
From the Vedude42/RAM-RandomAccessMacropad repository on GitHub, at the commit this page was made from: the board is PCB Files/RAM.kicad_pcb and its schematic PCB Files/RAM.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RAM design in my own project?
Its repository states no licence, so its author keeps all rights: ask Vedude42 before reusing the design.
