Questions

How big is the Sumo Robot PCB?

It measures 91 × 84.5 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Sumo Robot use?

63 parts, built around the AMS1117-3.3. 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 Sumo Robot KiCad files?

From the EZam1992/Sumo_Robot_PCBA repository on GitHub, at the commit this page was made from: the board is Sumo_Robot.kicad_pcb and its schematic Sumo_Robot.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Sumo Robot design in my own project?

Its repository states no licence, so its author keeps all rights: ask EZam1992 before reusing the design.
