Questions
How big is the Mimo PCB?
It measures 45 × 35 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mimo 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 Mimo KiCad files?
From the hamzaa-exe/Mimo repository on GitHub, at the commit this page was made from: the board is PCB/Mimo.kicad_pcb and its schematic PCB/Mimo.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mimo 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).
