Questions
How big is the ΜSpot PCB?
It measures 80 × 35 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ΜSpot use?
57 parts, built around the ATTINY404-SSN, AP65111AWU, FAN3111ESX and PSMN0R9-30YLDX. 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 ΜSpot KiCad files?
From the magborresen/uSpot repository on GitHub, at the commit this page was made from: the board is µSpot.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ΜSpot design in my own project?
Its repository states no licence, so its author keeps all rights: ask magborresen before reusing the design.
