Diatone Mamba MK4 F722 (MPU6000) + Reactor 44 BL32

Mamba MK4 F722 + Reactor 44 BL32 Mini is a powerful stack for small 3-5" drones.

The Mamba MK4 F722 Mini flight controller is one of the best that Diatone has to offer. The board uses a STM32F722 processor, has 16MB memory for blackbox, barometer, 6 UARTs, I2C port for magnetometer connection, 8 outputs for motors, TVS diode, 5V and 9V BEC, where 9V BEC can be turned on and off and connector for DJI FPV connection. The Mamba MK4 series has large soldering pads compared to other boards. This makes building and maintaining the drone a bit easier. A big advantage is the MPU6000 gyro.

The stack is complemented by a powerful Reactor 44 ESC that uses BlHeli_32 firmware and supports frequencies up to 128KHz, ensuring smooth and efficient motor operation even at high speeds. The ECS supports telemetry and includes a current sensor. Even with the small size of the ESC, large MOSFETs are used. The maximum current is 44A per channel. When using a 6S battery, a capacitor must be connected.
