Questions

How big is the Lego robot PCB?

It measures 99.1 × 99.1 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Lego robot use?

9 parts, built around the L80-M39, BD65496MUV-E2 and ICM-20948. 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 Lego robot KiCad files?

From the legokor/Navigacio_PCB repository on GitHub, at the commit this page was made from: the board is lego_robot.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Lego robot design in my own project?

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