Questions
How big is the Latchup badge PCB?
It measures 85.7 × 54 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Latchup badge use?
59 parts, built around the ICE40UP5K-SG48ITR50, M25PX32-VMW6E, ASE-12.000MHZ-ET and CDBU0520. 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 Latchup badge KiCad files?
From the mwelling/latchup-badge repository on GitHub, at the commit this page was made from: the board is latchup-badge.kicad_pcb and its schematic latchup-badge.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Latchup badge design in my own project?
Its repository states no licence, so its author keeps all rights: ask mwelling before reusing the design.
