Questions
How big is the Mega PCB?
It measures 49.3 × 51.8 mm and has 4 copper layers, 1.62 mm thick.
What parts does the Mega use?
52 parts, built around the RP2350B, AD5683RACPZ-2RL7, ADC122S021CIMM and W25Q128JVPIQ. 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 Mega KiCad files?
From the 1vers1on/Mega repository on GitHub, at the commit this page was made from: the board is mega.kicad_pcb and its schematic mega.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mega design in my own project?
Its repository states no licence, so its author keeps all rights: ask 1vers1on before reusing the design.
