Questions
How big is the Closed deck x4 PCB?
It measures 115.5 × 96.2 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Closed deck x4 use?
245 parts, built around the IXDN602PI, CH340N, KP234 and SRV05-4-P-T7. 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 Closed deck x4 KiCad files?
From the OpenLogicEFI/Hardware repository on GitHub, at the commit this page was made from: the board is Engine Managment/Closed Deck/Closed Deck x4/RevB2/closed-deck-x4.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Closed deck x4 design in my own project?
Its repository states no licence, so its author keeps all rights: ask OpenLogicEFI before reusing the design.
