Speedybee F405 V4 + 55A BLS is a combination of a flight controller and ESCs with a great price/performance ratio. The FC is packed with features. The basis of the FC is the F405 processor with ICM42688P gyro. The main features 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 an empty 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.
The board comes with a SpeedyBee 55A ESCs with BlHeli_S firmware. The ESCs can handle up to 55A current, making it suitable for classic 5" racing and freestyle drones. It includes a TVS diode to protect it from voltage spikes. Also included is an XT60 with cable and a 1000uF low ESR capacitor.
Compared to the previous version, the board uses a better gyro, compatibility with SD cards (C6 and C10) has been improved, it has a stronger BEC and stronger controllers with an aluminum heat sink are used.
