SpeedyBee F405 V4 Flight Controller

Overview:

The SpeedyBee F405 V4 Flight Controller is a engineered to provide unparalleled control and stability for FPV drones. It is equipped with an STM32F405 MCU and an ICM42688P IMU (Gyro), ensuring rapid processing and precise flight data. The Type-C USB port facilitates quick and easy connectivity, while the built-in barometer and AT7456E OSD chip enhance navigation and flight data display.

With BLE Bluetooth support, the flight controller allows for convenient wireless configuration. The 6-pin HD FPV Connector is compatible with a range of digital video transmission systems. The board also features a MicroSD Card Slot for blackbox logging and supports a power input of 3S to 6S Lipo batteries.

The SpeedyBee F405 V4 Flight Controller boasts multiple BEC outputs, including 5V, 9V, 3.3V, and 4.5V, catering to various peripheral needs. It also provides 8 ESC signal motor outputs, ensuring compatibility with a wide array of ESCs.
