Questions
How big is the Alphax 2ch PCB?
It measures 87 × 106 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Alphax 2ch use?
172 parts, built around the MPXHZ6400AC6T1, 1N4148WS, AO3400A and B5819W. 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 Alphax 2ch KiCad files?
From the rusefi/alphax-2chan repository on GitHub, at the commit this page was made from: the board is alphax_2ch.kicad_pcb and its schematic DOUBLE_PU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Alphax 2ch design in my own project?
Its repository states no licence, so its author keeps all rights: ask rusefi before reusing the design.
