Questions
How big is the 4x5 PCB?
It measures 57.1 × 60.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 4x5 use?
30 parts, built around the ATMEGA32U4-AU. 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 4x5 KiCad files?
From the drewkeys/4x5-Macropad repository on GitHub, at the commit this page was made from: the board is 4x5.kicad_pcb and its schematic 4x5.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 4x5 design in my own project?
Its repository states no licence, so its author keeps all rights: ask drewkeys before reusing the design.
