Questions
How big is the EngineControlUnit PCB?
It measures 65 × 56 mm and has 2 copper layers, 1.6 mm thick.
What parts does the EngineControlUnit use?
40 parts, built around the LM7808CT, CD1206-S01575 and MMBT3904. 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 EngineControlUnit KiCad files?
From the durmiel/EngineControlUnit repository on GitHub, at the commit this page was made from: the board is PCB/EngineControlUnit.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the EngineControlUnit design in my own project?
Its repository states no licence, so its author keeps all rights: ask durmiel before reusing the design.
