Flywoo GOKU GN405 Nano 35A STACK (16*16)

The Flywoo GOKU GN405 Nano 35A Stack is an incredibly powerful, ultra-compact electronics system engineered for high-performance micro FPV platforms, including premium cinewhoops, toothpicks, and long-range micro builds. Despite its tiny 16x16mm mounting footprint, this stack features full-scale hardware specs, packing an STM32F405 processor, an upgraded high-precision gyro, an SPL06 barometer, a 16MB Blackbox flash chip, and a heavy-duty 35A continuous current rating.

Supporting a wide 2–6S LiPo power band, this stack allows micro pilots to run extreme high-voltage setups with heavy motor loads without sacrificing frame space or adding bulk.

Features

Extreme Power in a Micro Footprint: Rare 35A rating on a tiny 16x16mm profile, perfect for handling high-KV motors on aggressive micro builds.

Pro-Tier Processing Core: Features an STM32F405 BGA processor to easily manage complex PID loops, dynamic filtering, and custom firmware configurations.

Upgraded Sensor Suite: Outfitted with an upgraded, high-vibration tolerance gyroscope for silky-smooth tracking alongside an SPL06 barometer for precise altitude data.

Massive Connectivity Layout: Provides 6 full hardware UART ports—exceptional for a nano-class stack—allowing hassle-free connections for GPS modules, serial receivers, and digital video transmitters.

Clean Power Infrastructure: Equipped with an onboard LC filter to screen out electrical noise, delivering stable, clean voltage to external components.
