Questions
How big is the RP2040 Module34D PCB?
It measures 34 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RP2040 Module34D use?
48 parts, built around the RP2040, W25Q128JVSIQ, 74LVC1T45W6 and PRTR5V0U2X. 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 Module34D KiCad files?
From the phpbbireland/echo repository on GitHub, at the commit this page was made from: the board is Module34D/RP2040_Module34D.kicad_pcb and its schematic 34 Pin Extender Board/adapter64.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RP2040 Module34D design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
