Questions
How big is the Macropad PCB?
It measures 71.6 × 108.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macropad use?
23 parts, built around the PCF8574DW and 1N4148W. 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 Macropad KiCad files?
From the imhwinters/Macropad repository on GitHub, at the commit this page was made from: the board is Macropad/_restore_backup_2026-07-27T09-34-51-010/Macropad.kicad_pcb and its schematic Macropad/Macropad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Macropad design in my own project?
Its repository states no licence, so its author keeps all rights: ask imhwinters before reusing the design.
