Questions
How big is the Schem 1 PCB?
It measures 80 × 40 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Schem 1 use?
90 parts, built around the XC6206-1.2V, XC6206-2.8V, XC6210B332MR and PMEG2005EGWX. 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 Schem 1 KiCad files?
From the can-caglar/dashcam repository on GitHub, at the commit this page was made from: the board is hardware/schem_1/schem_1.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Schem 1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask can-caglar before reusing the design.
