The Flywoo GOKU F405 SE 3–4S 20A AIO is a compact all-in-one flight controller and ESC solution for lightweight 2" and 2.5" micro FPV drones. With an STM32F405 MCU, MPU6000 gyro, integrated 20A 4-in-1 ESC, and direct support for DJI O4 / O4 Pro Air Unit, Walksnail, and HDZero, this board is ideal for clean, modern HD builds with minimal wiring.
Weighing only 6.5g, with 20×20mm mounting holes, 8MB blackbox memory, and support for Betaflight and INAV, the GOKU F405 SE AIO is perfectly suited for compact, powerful 3–4S builds such as the Firefly 25mini 3S, Firefly 20pro 4S, or similar micro FPV copters.
Features
- Ultra-lightweight design: 20 x 20mm mounting holes and a weight of only 6.5g, specifically optimized for the Firefly 25mini 3S and 20pro 4S.
- Powerful AIO configuration: F405 flight controller, 20A 4-in-1 ESC, 8MB blackbox, and barometer on a single board.
- Plug-and-play HD FPV: Dual BEC (10V/2A + 5V/2A) for direct connection to the DJI O4 / Air Unit, with no additional regulators required.
- High performance: 20A continuous current / 25A peak current, supports 3-4S LiPo batteries.
- Durable: 6-layer gold-plated PCB, stable operation from -20°C to 50°C.
