Questions
How big is the ICM PCB?
It measures 54.1 × 27.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ICM use?
9 parts, built around the ISL9V3040P3. 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 ICM KiCad files?
From the OpenLogicEFI/Hardware repository on GitHub, at the commit this page was made from: the board is Modules/Ignition Control Module/ICM2/RevB/ICM.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ICM design in my own project?
Its repository states no licence, so its author keeps all rights: ask OpenLogicEFI before reusing the design.
