Questions
How big is the Module c2 PCB?
It measures 76 × 40 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Module c2 use?
43 parts, built around the ESP32-S3-WROOM-1-N8, 74HC165D, AP2151WG and LM66100DCK. 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 Module c2 KiCad files?
From the TommyPersson/modular-keypads repository on GitHub, at the commit this page was made from: the board is pcb/module-c/main-board-r2/module-c2.kicad_pcb and its schematic pcb/epaper-driver/epaper-driver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Module c2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask TommyPersson before reusing the design.
