Questions
How big is the Robot pcb PCB?
It measures 140 × 180 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Robot pcb use?
297 parts, built around the STCS1APUR, DMG2305UX-7, CSD17578Q5A and WS2812B-2020. 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 pcb KiCad files?
From the Wet-Lettuce-Robocup/robot_pcb repository on GitHub, at the commit this page was made from: the board is robot_pcb.kicad_pcb and its schematic MotorDriver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Robot pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask Wet-Lettuce-Robocup before reusing the design.
