Diatone Mamba MK4 F722 (ICM42688) + Reactor 66 BL32 Mini

Mamba MK4 F722 + Reactor 66 BL32 Mini is a top-tier stack for high-performance racing and freestyle drones.

The Mamba MK4 F722 Mini flight controller is among the best Diatone has to offer. It features an STM32F722 processor with the ICM42688 gyro. It includes 16MB blackbox memory, a barometer, 6 UARTs, an I2C port for magnetometer connection, 8 motor outputs, a TVS diode, and both 5V and 9V BECs. The 9V BEC can be switched on/off via the connector for DJI FPV systems. The MK4 series features large solder pads, making the build and maintenance of the drone easier.

The stack is paired with the powerful Reactor 66 ESC, which runs BlHeli_32 firmware and supports frequencies up to 128KHz, ensuring smooth and efficient motor operation even at high RPMs. The ESC supports telemetry and includes a current sensor. Despite its compact size, it uses large MOSFETs and supports up to 66A per channel, making it suitable for all standard 2207 motors used in 5" drones. A capacitor must be used with 6S batteries.
