Flywoo GOKU F405 HD SE 3-4S 20A AIO Plug and Play O4/ O4 Pro 20x20mm for Firefly 20Pro / 25mini Micro FPV Drone FW5268

Specifications
Micro FPV enthusiasts have long struggled with tedious assembly, messy wiring, excessive soldering, and the trade-off between flight controller performance and weight.

Our GOKU F405 SE 3-4S 20A AIO solves all these. Designed specifically for 2-inch and 2.5-inch drones with deep compatibility for Firefly 25mini 3S and Firefly 20pro 4S, it reimagines HD FPV building and flying.

Powered by STM32F405 and ICM42688-P/ MPU6000 / BMI270 gyro for responsive, butter-smooth control. Features dedicated dual BEC for direct DJI O4 Air Unit connection on 3-4S (no extra BEC needed). Full plug-and-play ports mean only motor wires require soldering – easy even for beginners. At just 6.5g with standard 20×20mm mounting, it delivers the perfect balance of functionality and lightness.

Highlights:
1. Butter-Smooth Flight – STM32F405 MCU for ultra-responsive, jitter-free control
2. Powerful & Efficient – 20A continuous / 25A peak current, supports 3-4S LiPo batteries
3. Plug-and-Play HD FPV – Dual BEC (10V/2A + 5V/2A) for direct DJI O4/Air Unit connection, no extra regulators needed
4. Beginner-Friendly Build – Full plug-and-play ports, only motor wires require soldering
5. Ultra-Light & Compact – 20×20mm standard footprint, only 6.5g, deeply optimized for Firefly 25mini 3S & 20pro 4S
6. Unlimited Flight Modes – Onboard 8MB black box, supports Betaflight/INAV dual firmware
7. Hassle-Free Tuning – Bottom-mounted vertical Type-C port, no disassembly needed for firmware flashing
8. Built to Last – 6-layer gold-plated PCB, stable operation from -20°C to 50°C
