Questions
How big is the Lambda x2 PCB?
It measures 81.9 × 95 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Lambda x2 use?
291 parts, built around the GS8332-SR, TJA1051T/3/1, MCP6002T-I/SN(MS) and MAX31855KASA+T. 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 Lambda x2 KiCad files?
From the rusefi/rusefi-hardware repository on GitHub, at the commit this page was made from: the board is lambda-x2/lambda-x2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lambda x2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask rusefi before reusing the design.
