Mini Carrier Board has the standardized DF17 connector which allows user to connect it to every version of the Cube flight controller. With smaller size and almost the same capability with Pixhawk 2.1 standard carrier board, it can better fit-in to those applications which have size limits. Also, it can be equipped with the Cube Mini to better fulfill the requests from customers.
Functionality of Carrier Board:
Dual power input (for redundant power, automatic switch to another power when one fails)
Power distribution (limit the current at each connector, avoiding overloading when one device draws too large current)
Voltage protection (over or under voltage protection, the circuit will be shut down if the voltage exceeds the limit)
