Questions
How big is the Compute PCB?
It measures 88.4 × 63.6 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Compute use?
125 parts, built around the TMC2209-LA-T, MCP1700-1502E/TO, USBLC6-2SC6 and SS24FL. 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 Compute KiCad files?
From the hstarmans/firestarter repository on GitHub, at the commit this page was made from: the board is base/compute.kicad_pcb and its schematic base/camera.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Compute design in my own project?
Its repository states no licence, so its author keeps all rights: ask hstarmans before reusing the design.
