Questions
How big is the RP2040Micro PCB?
It measures 31 × 18 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RP2040Micro use?
39 parts, built around the RP2040, W25Q16JVSSIQ, AMS1117-3.3 and D22. 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 RP2040Micro KiCad files?
From the elral/PCB_RP2040Micro repository on GitHub, at the commit this page was made from: the board is RP2040Micro.kicad_pcb and its schematic RP2040.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RP2040Micro design in my own project?
Its repository states no licence, so its author keeps all rights: ask elral before reusing the design.
