Diatone Mamba MK4 F722 APP + F55A 128K BL32

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

The Mamba MK4 F722 APP flight controller is one of the best Diatone has to offer. The board uses the STM32F722 processor and the reliable MPU6000 gyro, has 16MB blackbox memory, barometer,6 UARTs, I2C port for magnetometer connection, 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 flight controller conveniently without plugging in a cable. For example, SpeedyBee app via your phone.

The stack is complemented by a powerful F55 ESC that uses BlHeli_32 firmware and supports up to 128KH frequency, ensuring smooth and efficient motor operation even at high speeds. The ESC supports telemetry and includes a current sensor. The ESC maximum current is 55A per channel, making it easily handle all classic 2207 motors used on 5" drones. When using a 6S battery, a capacitor must be connected. For better heat dissipation, the ESC has an aluminum heatsink. This also protects sensitive components from mechanical damage and dirt.
