Questions
How big is the 6in-6out PCB?
It measures 150 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 6in-6out use?
227 parts, built around the CH340C, ESP32-WROOM-32U, LTV-847 and AMS1117-3.3. 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 6in-6out KiCad files?
From the Oopsan204/IO_ISOLATOR_16INOUT repository on GitHub, at the commit this page was made from: the board is 6in-6out/6in-6out.kicad_pcb and its schematic 6in-6out/6in-6out.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 6in-6out design in my own project?
Its repository states no licence, so its author keeps all rights: ask Oopsan204 before reusing the design.
