Mamba MK4 F722 APP + F55 128K BL32 is a powerful stack for racing and freestyle 5-7" drones.

The Mamba MK4 F722 APP flight controller is one of the best Diatone has to offer. The board uses the STM32F722 processor, the popular MPU6000 gyro, features 16MB blackbox memory, barometer,6 UARTs, I2C port for magnetometer, 8 outputs for motors, TVS diode, 5V and 9V BEC, where 9V BEC can be switched by DJI FPV connector. The Mamba MK4 series has large soldering surfaces compared to other boards. This makes building and maintaining the drone a bit easier. The APP series will also offer an integrated Wifi module, so you can set up the controller conveniently without plugging in a cable. For example with the SpeedyBee app via your phone.

The stack is complemented by a powerful F65 ESCs that uses BlHeli_32 firmware and supports frequency up to 128KH, ensuring smooth and efficient motor operation even at high speeds. The ESC supports telemetry and includes a current sensor. The maximum current is 65A per channel, making it easily handle larger 2809 motors used on 7" drones or cinelifters. When using a 6S battery, a capacitor must be connected. For better heat dissipation, the controller has an aluminum heat sink. This also protects sensitive components from mechanical damage and dirt.
