Questions
How big is the 92pi PCB?
It measures 201.7 × 112.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 92pi use?
229 parts, built around the RP2040, AP2112K-3.3, 1N914WT and SI2301. 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 92pi KiCad files?
From the hexmaster111/92pi repository on GitHub, at the commit this page was made from: the board is PCB/92pi/92pi.kicad_pcb and its schematic PCB/92pi/92pi.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 92pi design in my own project?
Its repository states no licence, so its author keeps all rights: ask hexmaster111 before reusing the design.
