The Diatone Mamba MK4 H743 V2 FC is the best of Diatone's FCs. The board uses a powerful STM32H743 processor in combination with a pair of ICM-42688-P gyroscopes. The gyroscopes are rotated 90° to each other. Betaflight uses data fusion, where it combines both outputs from the gyroscopes. This helps filter out unwanted vibrations and interference. Another advantage is the large 128MB memory for the blackbox (16MB is normally used). The board has 8 UARTs for connecting various peripherals. Of course, there is a barometer, I2C for connecting a magnetometer, 8 outputs for motors, 5V and 9V switched BEC, TVS Diode and a connector for DJI FPV connection. Like the APP series, this board also has an integrated Wifi module for easy wireless setup. So you can set the board, for example, via the phone via the SpeedyBee APP.
