Overview
The Flywoo GOKU HD745 EVO is a 40A AIO flight controller with integrated 4-in-1 ESC (AM32), designed for compact FPV builds including ultralight quad setups. It uses an STM32F745 (216MHz) MCU with 1MB flash, includes dual BEC outputs (5V/9V), and provides multiple UARTs plus onboard blackbox memory.
Key Features
- STM32F745 BGA MCU, 216MHz, 1MB flash
- Integrated 40A 4-in-1 ESC with AM32 firmware
- Dual BEC: 9V and 5V power outputs
- Gyro: ICM42688; Barometer: BMP280
- Onboard WS2812 LEDs (WS2812*4)
- USB VCP driver (USB does not take up a UART; all UARTs usable simultaneously)
- 7 hardware UARTs: UART1/2/3/4/5/6/7
- Supports serial receivers only: SBUS, iBus, Spektrum, Crossfire (PPM/PWM not supported)
- Onboard blackbox logging memory: 8Mbytes
- Plug&Play positioning stated for O4 / O4 Pro
