Flywoo GOKU GN405 Nano HD 20A Stack V3 with ELRS

The Flywoo GOKU GN405 Nano HD 20A Stack V3 delivers robust processing and system integration in a standard 16x16mm micro footprint. Designed for 2-inch to 3-inch micro builds and cinewhoops, this stack combines an F405 flight controller with a 20A 4-in-1 ESC. With a built-in ExpressLRS receiver and native plug-and-play ports for digital FPV systems, it dramatically reduces wiring complexity and saves crucial weight on sub-250g builds.

Key features

• Digital FPV ready: Includes a dedicated BEC and plug-and-play connector for direct integration with DJI O3, Walksnail, and Caddx Vista video transmitters.
• Integrated control link: The onboard serial ExpressLRS receiver provides long-range, low-latency control without the bulk or wiring of an external board.
• F405 processing: Handles advanced Betaflight filtering and higher PID loop rates more efficiently than standard micro F411 equivalents.
• Micro mounting footprint: Built on a standard 16x16mm hole pattern tailored for ultra-compact micro frames.

Specifications

• Processor: STM32F405
• Continuous current: 20 A
• Onboard receiver: ELRS (Serial)
• Mounting size: 16x16 mm
• Supported firmware: Betaflight

This stack is an ideal choice for drone builders assembling lightweight digital whoops or micro freestyle frames where internal space is extremely limited but advanced processing and crisp HD video are required.
