Questions
How big is the Keyey PCB?
It measures 304.8 × 125.5 mm and has 4 copper layers, 1.2 mm thick.
What parts does the Keyey use?
376 parts, built around the RP2040, W25Q128JVSIQ, SK6812MINI-E and 1N4148W. 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 Keyey KiCad files?
From the Thenewtechgu/Keyey repository on GitHub, at the commit this page was made from: the board is Keyey/Keyey.kicad_pcb and its schematic Keyey/Keyey.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keyey design in my own project?
Its repository states no licence, so its author keeps all rights: ask Thenewtechgu before reusing the design.
