Speedybee F405 V3 is a feature-packed flight controller with a great price/performance ratio. The core of the controller is the F405 processor with BMI270 gyro. The main advantages of the board are the integrated bluetooth module for wireless setup, SD card slot for blackbox log recording, integrated barometer and support for 8 motor outputs.LED outputs are located in the corners of the board for easy installation. The LEDs can be controlled classically via betaflight or by the integrated LED controller. Another interesting feature is the 4 LEDs on the edge of the board which indicate the battery level. This way you can see at a glance if you are putting a dead battery in the drone. The board has a connector for connecting DJI FPV as well as I2C pins for connecting a compass. There is both a 5V and 9V BEC.
