Questions
How big is the Badge PCB?
It measures 95 × 147.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Badge use?
124 parts, built around the ESP32-C3-MINI-1-N4, MFRC522B, MT3608 and 74HC165M/TR. 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 Badge KiCad files?
From the hackthenorth/badge-hardware repository on GitHub, at the commit this page was made from: the board is badge.kicad_pcb and its schematic badge.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Badge design in my own project?
Its repository states no licence, so its author keeps all rights: ask hackthenorth before reusing the design.
