Questions
What parts does the RoboSphere use?
9 parts, built around the L293D and RASPBERRY PI ZERO 2 W. 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 RoboSphere KiCad files?
From the Engarix/RoboSphere repository on GitHub, at the commit this page was made from: the board is RoboSphere/RoboSphere.kicad_pcb and its schematic RoboSphere/RoboSphere.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RoboSphere design in my own project?
Its repository states no licence, so its author keeps all rights: ask Engarix before reusing the design.
