Questions
How big is the MiniMicro PCB?
It measures 50.8 × 41.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MiniMicro use?
43 parts, built around the ATTINY3227-MU, CAHCT1G125QDCKRQ1, CD74HC4050MT and BMP390. 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 MiniMicro KiCad files?
From the OrenBee/FlightControlBoard repository on GitHub, at the commit this page was made from: the board is MiniMicro/MiniMicro.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the MiniMicro design in my own project?
Its repository states no licence, so its author keeps all rights: ask OrenBee before reusing the design.
