Questions
How big is the Obd2 PCB?
It measures 80 × 49 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Obd2 use?
64 parts, built around the MCP2561-E/P, MC33660BEF, LD1117 and LTV-816. 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 Obd2 KiCad files?
From the kevinkrieger/CAN repository on GitHub, at the commit this page was made from: the board is obd2-v2/obd2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Obd2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask kevinkrieger before reusing the design.
