Questions
How big is the Eric robots PCB?
It measures 50 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Eric robots use?
28 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 Eric robots KiCad files?
From the har224466/pcb_designs repository on GitHub, at the commit this page was made from: the board is eric_robots.kicad_pcb and its schematic eric_robots.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Eric robots design in my own project?
Its repository states no licence, so its author keeps all rights: ask har224466 before reusing the design.
