Questions
How big is the Connector board PCB?
It measures 76 × 135 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Connector board use?
62 parts, built around the AP2171WG and F3311A7H121024E200. 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 Connector board KiCad files?
From the TommyPersson/modular-keypads repository on GitHub, at the commit this page was made from: the board is pcb/module-c/connector-board-r2/connector-board.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 Connector board design in my own project?
Its repository states no licence, so its author keeps all rights: ask TommyPersson before reusing the design.
