Questions
How big is the Mouse PCB?
It measures 41.5 × 59 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mouse use?
34 parts, built around the E73-2G4M08S1C, MDBT50Q-1MV2, USBLC6-2SC6 and PESD5V0S1UL. 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 Mouse KiCad files?
From the komeed/mouse repository on GitHub, at the commit this page was made from: the board is pcb/mouse/mouse.kicad_pcb and its schematic pcb/mouse/mouse.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mouse design in my own project?
Its repository states no licence, so its author keeps all rights: ask komeed before reusing the design.
