Questions

How big is the Hexapod pcb PCB?

It measures 65 × 56.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Hexapod pcb use?

15 parts. 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 Hexapod pcb KiCad files?

From the Hexapod-SOC/hexapod-pcb repository on GitHub, at the commit this page was made from: the board is hexapodpcb.kicad_pcb and its schematic hexapodpcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Hexapod pcb design in my own project?

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