Flywoo GOKU GN745 V3 45A AIO Flight Controller 32bit AM32 Type-C Plug&Play for O4 / O4 Pro

Overview

The Flywoo GOKU GN745 45A AIO is a 32-bit AIO flight controller with onboard 4-in-1 ESC, updated to the V3 version with a new ESC two-in-one drive solution, direct-plug UART ports, and a Type-C connector. It is designed for Plug & Play builds and is compatible with Betaflight (BF), INAV, and Ardupilot, and supports connection to O3 air unit, GPS, camera, analog VTX, and receiver without soldering (with supported cable harnesses).

Note: The O4 lite can handle a max voltage of 1-3S. When using a 4-6S (or higher) battery, an extra 5V BEC is required.

Key Features

• MCU: STM32F745 BGA, 32-bit, 216MHz, 1MB Flash
• Gyro: MPU6000
• Type-C interface
• OSD: AT7456E
• USB VCP driver (USB does not take up a UART; all UARTs usable simultaneously)
• 7 hardware UARTs: UART1, UART2, UART3, UART4, UART5, UART6, UART7
• I2C supported
• Onboard blackbox logging: 16Mbytes (also listed as 16mb)
• Serial receivers supported: SBUS, iBus, Spektrum, Crossfire (PPM and PWM receivers not supported)
• ESC supports AM32 and bidirectional DSHOT (stated); ESC control/driver uses an integrated AT32 chip (stated)
• Multilayer board design: 8-layer 3OZ PCB (stated)
• Larger motor pad area (stated as +30% vs V2) with improved overcurrent protection (stated)

Details

The Flywoo GOKU GN745 V3 AIO flight controller features clearly labeled motor pads (M1–M4) and power pads for straightforward wiring.

The Flywoo GOKU GN745 V3 AIO flight controller features clearly marked battery pads and a side USB port for convenient setup and configuration.

The Flywoo GOKU GN745 V3 AIO combines a 45A ESC with a USB-C port, F745 MCU, and MPU6000 gyroscope for streamlined builds.

The Flywoo GOKU GN745 V3 45A AIO pairs an STM32F745 MCU with a Type‑C port, larger solder pads, and Betaflight/INAV/Ardupilot compatibility.

The GOKU GN745 V3 AIO uses clearly labeled pads for camera/VTX connections, receiver SBUS, and power (5V, GND, BAT) to simplify wiring.

Clearly labeled VBAT, 5V/4.5V/3.3V, GND, CAM/VTX, UART TX/RX, and USB pads help simplify wiring for a clean FPV build.

The package includes a capacitor, XT30 power lead, shock-absorbing mounting hardware, and wiring harnesses for DJI O3, receiver, camera/VTX, and GPS (with compass).
