Questions
How big is the Modxo Mega PCB?
It measures 42 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Modxo Mega use?
50 parts, built around the RP2040, W25Q128JVSIQ, AP2112K-3.3TRG1 and 1N5819WS. 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 Modxo Mega KiCad files?
From the clegg89/Modxo-Designs repository on GitHub, at the commit this page was made from: the board is Modxo-Mega/Modxo-Mega.kicad_pcb and its schematic Modxo-Mega/Modxo-Mega.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Modxo Mega design in my own project?
Its repository states no licence, so its author keeps all rights: ask clegg89 before reusing the design.
