CubePilot Cube Purple (also known as Cube Mini) is an autopilot system designed specifically for land-based applications such as boats, cars, or rovers. This flight controller is based on the original Pixhawk 2.1 Cube Black main module, featuring an F4 chip, but offers a smaller platform suitable for situations where sensor redundancy isn't necessary. The Cube Purple Set, which includes a Mini Carrier board, serves as an optimal solution for compact drones. Moreover, it is compatible with both PX4 and APM firmware.
