Questions
How big is the Smartbed PCB?
It measures 59.5 × 51.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Smartbed use?
50 parts, built around the ATSAMD21J18A-AU, LD1117S33CTR-HXY and PRTR5V0U2X. 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 Smartbed KiCad files?
From the Xenosb/thesis-atmel repository on GitHub, at the commit this page was made from: the board is pcb/smartbed.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Smartbed design in my own project?
Its repository states no licence, so its author keeps all rights: ask Xenosb before reusing the design.
