Flywoo GOKU GN405 Nano HD 35A Stack V3 with ELRS

The Flywoo GOKU GN405 Nano HD V3 stack combines an F405 flight controller and a 35A 4-in-1 ESC into a compact 16x16mm footprint for 2-inch to 4-inch micro drones and sub-250g builds. Featuring an onboard ELRS receiver and dual BECs, it minimises soldering and external components while delivering the power needed for heavier micro freestyle or cinematic rigs.

Key features

• Plug-and-play connector for digital VTX units (DJI O3, Walksnail Avatar, Caddx Vista) via the dedicated 9V BEC.

• Integrated ELRS receiver saves weight, space, and wiring on cramped micro frames.

• Six hardware UARTs provide ample connectivity for GPS, compass, and digital HD video systems without port conflicts.

• Robust 35A continuous current overhead handles aggressive flying and high-kV motors on 2S to 6S micro setups.

Specifications

• Processor: STM32F405

• Gyro: ICM42688P

• Input voltage: 2-6S LiPo

• Continuous current: 35A

• BEC outputs: 5V 2A, 9V 2A

• UARTs: 6

• Mounting pattern: 16x16mm (M2 hardware)

• Supported firmware: Betaflight, INAV

By managing the ELRS link internally and offering direct HD VTX compatibility, this stack serves as a clean, low-profile foundation for powerful digital micro quadcopters.
