Questions
How big is the PillDispenser PCB?
It measures 234 × 117 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PillDispenser use?
364 parts, built around the ATMEGA328PB-AU, TPM8837E-DF4R, CH340G and TPS56637RPA. 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 PillDispenser KiCad files?
From the xPiTi/pillex-main repository on GitHub, at the commit this page was made from: the board is PCB/PillDispenser.kicad_pcb and its schematic PCB/PillDispenser.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PillDispenser design in my own project?
Its repository states no licence, so its author keeps all rights: ask xPiTi before reusing the design.
