Diatone Mamba MK4 F405 (MPU6000) + Reactor 44 BL32

Mamba MK4 F405 + Reactor 44 BL32 Mini is a powerful stack for small 3-5" drones.

The Mamba MK4 F405 Mini is the fourth generation flight controller, with the main advantage of larger solder pads and USB-C connector. It uses the F405 processor and the MPU6000 gyro, which supports a refresh rate of 8kHz. The board also includes 5V and 9V BEC, a barometer and 16MB memory for the blackbox. The board has raised I2C bus pads for compass connection. For protection against voltage spikes, the board has a TVS diode. Connecting the DJI O3 digital video transmission is simple via the connector.

The stack is complemented by a powerful Reactor 44 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. Even with the small size of the ESC, large MOSFETs are used. The maximum current of the ESC is 44A per channel. When using a 6S battery, a capacitor must be connected.
