Questions
How big is the RP2350B RM2-module PCB?
It measures 33.7 × 68.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the RP2350B RM2-module use?
63 parts, built around the W25Q128JVSIQ, AP2112K-3.3, APS6404L-3SQN-SN 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 RP2350B RM2-module KiCad files?
From the Pico-Framework/RP2350B-RM2-module repository on GitHub, at the commit this page was made from: the board is RP2350B-RM2-module.kicad_pcb and its schematic RP2350B-RM2-module.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RP2350B RM2-module design in my own project?
Its repository states no licence, so its author keeps all rights: ask Pico-Framework before reusing the design.
