Mamba MK4 F722 Mini is a powerful flight controller for racing and freestyle 5" drones.
The Mamba MK4 F722 Mini flight controller is one of the best offerings from Diatone. The board uses an STM32F722 processor and gyro ICM42688. It also features 16MB memory for blackbox, a barometer, 6 UARTs, an I2C port for connecting a magnetometer, 8 outputs for motors, TVS diode, and 5V and 9V BEC, where the 9V BEC can be switched with a connector for connecting DJI FPV. The Mamba MK4 series has large solder pads compared to other boards, making the construction and maintenance of the drone somewhat easier.
