Questions
How big is the RoPlug PCB?
It measures 24 × 27.2 mm and has 2 copper layers, 0.8 mm thick.
What parts does the RoPlug use?
17 parts, built around the ATMEGA32U4-MU. 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 RoPlug KiCad files?
From the mrwm/roPlug repository on GitHub, at the commit this page was made from: the board is roPlug.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the RoPlug design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
