Flywoo GOKU F405 HD 3-4S 20A AIO (FC+ESC+ELRS RX)

Flywoo GOKU F405 HD is an AIO board combining flight controller, 20A ESCs, and ELRS receiver. The board is suitable for smaller 2–3" drones powered by 3–4S LiPo batteries. The board is designed for use with digital video transmission and is not equipped with an analog OSD chip. The board supports Betaflight and iNav firmware.

The flight controller uses the STM32F405BGA processor combined with the ICM42688P gyro. The board features a SPL06 barometer for altitude measurement and 16MB memory for blackbox and a 5V/2A BEC for powering peripherals. The board includes a connector for easy GPS module connection, with an I2C bus for connecting a compass. A second connector is used for easy connection of digital video transmitters powered by battery voltage. Power to the video transmitter can be turned off using a switch on the radio. This feature is appreciated when waiting for GPS satellite fix, avoiding VTX overheating on the ground. The function must be enabled in the board’s firmware.

The ESCs use Bluejay firmware, supporting bidirectional dshot. The ESCs can handle up to 20A per channel. Motors can be soldered to the AIO board or connected via the included connectors. The board is equipped with a current sensor.

The integrated ELRS receiver operates on 2.4GHz and connects via the UART1 interface. The receiver uses an external antenna connected via an IPEX1 connector.

The board has mounting holes with a spacing of 25.5x25.5mm. External dimensions are 30×30×10mm with a weight of 5.2 grams. The package includes a cable with an XT30 connector.
