Questions
How big is the Rp2040 devboard PCB?
It measures 22 × 54 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rp2040 devboard use?
33 parts, built around the RP2040 and W25Q128JVSIQ. 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 devboard KiCad files?
From the shelxty/rp2040_devboard repository on GitHub, at the commit this page was made from: the board is rp2040_devboard.kicad_pcb and its schematic rp2040_devboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rp2040 devboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask shelxty before reusing the design.
