Questions
How big is the LED Badge PCB?
It measures 165.1 × 76.2 mm and has 4 copper layers, 1.6 mm thick.
What parts does the LED Badge use?
400 parts, built around the 74AHCT1G125SE, MTCH105-I/ST, L7805 and MPU-6000. 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 LED Badge KiCad files?
From the mjbella/LED_Badge repository on GitHub, at the commit this page was made from: the board is ledbadge.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LED Badge design in my own project?
Its repository states no licence, so its author keeps all rights: ask mjbella before reusing the design.
