ICRS/101
The all-new open source Robotics 101 course from ICRS. It's specifically designed to be run in hackspaces, after school clubs and university societies.

It measures 66 × 68.6 mm and has 2 copper layers, 1.6 mm thick.
99 parts, built around the ARDUINO UNO R3. 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.
From the Qeteshpony/FP2800A-Tester repository on GitHub, at the commit this page was made from: the board is pcb/FP2800A-Tester.kicad_pcb and its schematic pcb/FP2800A-Tester.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the BSD-2-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
