The Speedybee F405 V4 is a feature-packed flight controller with a great price/performance ratio. The core of the flight controller is the F405 processor with ICM42688P 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 motors. LED outputs are located in the corners of the board for easy installation. The LEDs can be controlled 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. Both 5V and 9V BEC are available.

Compared to the previous version, the board uses a better gyro, compatibility with SD cards (C6 and C10) has been improved and has a more powerful BEC.
