Questions
How big is the MSS Crossover PCB?
It measures 50.8 × 59.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MSS Crossover use?
20 parts, built around the TB003-500-P02BE, MJ3221-88-0, 2N3904TA and CF14JT470R. 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 KiCad files?
From the dabridgham/MSS-Crossover repository on GitHub, at the commit this page was made from: the board is mss-crossover.kicad_pcb and its schematic mss-crossover.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MSS Crossover design in my own project?
Its repository states no licence, so its author keeps all rights: ask dabridgham before reusing the design.
