Diatone Mamba MK4 F722 + F55A BL32

Mamba MK4 F722 + F55 128K BL32 is a high-performance stack designed for 5" racing and freestyle drones.

The flight controller features an STM32F722 processor and ICM42688P gyro, along with 16MB of blackbox memory, a barometer, 6 UART ports, an I2C port for connecting a magnetometer, and 8 motor outputs. It also includes a 5V and 9V BEC, where the 9V BEC can be switched via a dedicated DJI FPV connector. The Mamba MK4 series features enlarged solder pads, making drone assembly and maintenance significantly easier.

The stack is paired with the powerful F55 ESC running BlHeli_32 firmware, ensuring smooth and efficient motor control even at high RPMs. The ESC supports telemetry and includes a built-in current sensor. With a maximum continuous current of 55A per channel, it easily handles all standard 2207-size motors used in 5" builds. When using a 6S battery, a capacitor should be connected. For better heat dissipation, the ESC features an aluminum heatsink, which also protects sensitive components from mechanical damage and dust.
