Questions
How big is the Breakbeam processor PCB?
It measures 96.5 × 52.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Breakbeam processor use?
46 parts, built around the LD1117D33 and MMPQ3904. 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 Breakbeam processor KiCad files?
From the UBC-Thunderbots/Electrical repository on GitHub, at the commit this page was made from: the board is legacy/electronics/speedsensor/processor/breakbeam-processor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Breakbeam processor design in my own project?
Its repository states no licence, so its author keeps all rights: ask UBC-Thunderbots before reusing the design.
