Questions
How big is the FrogDev PCB?
It measures 21 × 51 mm and has 4 copper layers, 1.6 mm thick.
What parts does the FrogDev use?
46 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 FrogDev KiCad files?
From the frogtospace/FrogBoard repository on GitHub, at the commit this page was made from: the board is FrogDev.kicad_pcb and its schematic FrogDev.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FrogDev design in my own project?
Its repository states no licence, so its author keeps all rights: ask frogtospace before reusing the design.
