Questions
How big is the OE PyBoard PCB?
It measures 33 × 41.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the OE PyBoard use?
57 parts, built around the STM32F405RGT6, MCP1700T-3302E/TT(MS), CGA2B3X7R1H104K050BB and CRCW0402560RFKEDC. 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 OE PyBoard KiCad files?
From the oeps-tech/OE-PyBoard repository on GitHub, at the commit this page was made from: the board is PCB/OE PyBoard.kicad_pcb and its schematic PCB/OE PyBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the OE PyBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask oeps-tech before reusing the design.
