Questions
How big is the Ledboad PCB?
It measures 100 × 30.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Ledboad use?
305 parts, built around the FM6126C, CJX3139K and TS-1088-AR02016. 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 Ledboad KiCad files?
From the hspsh/cyberbadge repository on GitHub, at the commit this page was made from: the board is 2_0/ledboad/ledboad.kicad_pcb and its schematic 1_0/CyberBadge.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ledboad design in my own project?
Its repository states no licence, so its author keeps all rights: ask hspsh before reusing the design.
