It measures 45 × 45 mm and has 4 copper layers, 1.6 mm thick.
70 parts, built around the AP2112K-3.3, MBR0540, 1N5819WS and SI2371EDS. 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.
From the npgo22/sipm repository on GitHub, at the commit this page was made from: the board is sipm.kicad_pcb and its schematic sipm.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask npgo22 before reusing the design.

My first fully custom project inspired by the microbots from the movie Big Hero 6. My goal is to get into swarm robotics and I believe this is a HUGE leap in that direction, but a good moment to learn.
