Questions
How big is the V0.4Mini PCB?
It measures 99.8 × 94 mm and has 2 copper layers, 1.6 mm thick.
What parts does the V0.4Mini use?
66 parts, built around the LM2940S-5.0. 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 V0.4Mini KiCad files?
From the jeagan626/modEFI repository on GitHub, at the commit this page was made from: the board is V0.4 Mini/V0.4Mini/V0.4Mini.kicad_pcb and its schematic ModEFI_Mega/ArduinoMegaEcuJE/ArduinoMegaEcuJE.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the V0.4Mini design in my own project?
Its repository states no licence, so its author keeps all rights: ask jeagan626 before reusing the design.
