Questions
How big is the Robot PCB?
It measures 100 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Robot use?
186 parts, built around the LM5107SD, LD1117D33, 74HC4050D and BMG160. 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 Robot KiCad files?
From the UBC-Thunderbots/Electrical repository on GitHub, at the commit this page was made from: the board is legacy/electronics/robot/main/main.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Robot design in my own project?
Its repository states no licence, so its author keeps all rights: ask UBC-Thunderbots before reusing the design.
