Questions
How big is the Mss crossover array PCB?
It measures 88.9 × 215.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mss crossover array use?
291 parts, built around the ATTINY85-20SU, AP7381-33Y, TLP241A(F and 1210L020WR. 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 Mss crossover array KiCad files?
From the IowaScaledEngineering/mss-crossover repository on GitHub, at the commit this page was made from: the board is kicad/mss-crossover/mss-crossover-array.kicad_pcb and its schematic kicad/mss-crossover/mss-crossover.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mss crossover array design in my own project?
Its repository states no licence, so its author keeps all rights: ask IowaScaledEngineering before reusing the design.
