Questions
How big is the Dongle PCB?
It measures 67.3 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dongle use?
42 parts, built around the LD1117D33, BC847A and SD1209T3-A1. 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 Dongle KiCad files?
From the UBC-Thunderbots/Electrical repository on GitHub, at the commit this page was made from: the board is legacy/electronics/dongle/dongle.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dongle design in my own project?
Its repository states no licence, so its author keeps all rights: ask UBC-Thunderbots before reusing the design.
