Questions
How big is the Sub module programmer PCB?
It measures 127 × 50.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sub module programmer use?
41 parts, built around the 74AHCT1G125SE. 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 Sub module programmer KiCad files?
From the TommyPersson/modular-keypads repository on GitHub, at the commit this page was made from: the board is pcb/module-c/sub-module-programmer-r1/sub-module-programmer.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 Sub module programmer design in my own project?
Its repository states no licence, so its author keeps all rights: ask TommyPersson before reusing the design.
