Questions
How big is the SPU0410LR5H PCB?
It measures 20 × 15 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SPU0410LR5H use?
5 parts, built around the SPU0410LR5H-QB. 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 SPU0410LR5H KiCad files?
From the meerstern/SPU0410LR repository on GitHub, at the commit this page was made from: the board is SPU0410LR5H.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the SPU0410LR5H design in my own project?
Its repository states no licence, so its author keeps all rights: ask meerstern before reusing the design.
