Questions
How big is the Prius gen2 PCB?
It measures 147.8 × 65 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Prius gen2 use?
149 parts, built around the ESP32-WROOM-32, TJA1051T/3/1, MCP602-I/P and TDA2822D. 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 Prius gen2 KiCad files?
From the ksmola/PriusG2 repository on GitHub, at the commit this page was made from: the board is prius_gen2.kicad_pcb and its schematic communication.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Prius gen2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask ksmola before reusing the design.
