Questions
How big is the ArduinoPCB PCB?
It measures 123.2 × 100.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ArduinoPCB use?
32 parts, built around the PCA9685PW and MCP23017-E/SS. 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 ArduinoPCB KiCad files?
From the Viperinius/Chess-Robot repository on GitHub, at the commit this page was made from: the board is PCB/ArduinoPCB.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ArduinoPCB design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
