Questions
How big is the Rp2040 custom devboard PCB?
It measures 58 × 49.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Rp2040 custom devboard use?
35 parts, built around the RP2040, W25Q128JVSIQ and ABM8-272-T3. 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 custom devboard KiCad files?
From the guster32/rp2040_custom_devboard repository on GitHub, at the commit this page was made from: the board is rp2040_custom_devboard.kicad_pcb and its schematic rp2040_custom_devboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rp2040 custom devboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask guster32 before reusing the design.
