Questions
How big is the Optopi PCB?
It measures 100 × 80 mm and has 4 copper layers, 1.56 mm thick.
What parts does the Optopi use?
68 parts, built around the RP2040, ZGY133/T9(PLT), ZGY135/T9(PLR) 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 Optopi KiCad files?
From the Erhannis/Optopi repository on GitHub, at the commit this page was made from: the board is pcb/optopi.kicad_pcb and its schematic pcb/optic_uart.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Optopi design in my own project?
Its repository states no licence, so its author keeps all rights: ask Erhannis before reusing the design.
