Questions
How big is the Rp2040 base PCB?
It measures 265.4 × 111.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rp2040 base use?
177 parts, built around the RP2040, W25Q128JVSIQ, SRV05-4 and BAV70. 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 Rp2040 base KiCad files?
From the ScatteredDrifter/Mriya repository on GitHub, at the commit this page was made from: the board is pcb/rp2040_base.kicad_pcb and its schematic pcb/keeb_matrix.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rp2040 base design in my own project?
Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
