Mint

Mint Flight Controller Board is compact under a 27 mm square to fit on Micro/Nano class drones using a standard 20 x 20 mm mount. Despite the small form factor, it features a comprehensive set of IO interfaces for a wide range of peripherals.

This repository hosts the KiCAD project of the flight controller board.

• The PCB design is still under completion. This board has never been built and tested.
