Flywoo GOKU F405 HD 1-2S 12A AIO V2 Whoop Board

The Flywoo GOKU F405 HD V2 AIO upgrades lightweight 1-2S whoops and micro toothpicks to a much more capable flight controller architecture. By utilising an STM32F405 processor instead of a standard F411, this board provides the extra hardware UARTs required to easily run digital HD video systems like DJI O3, Walksnail Avatar, or HDZero alongside your RC link and GPS. It integrates a 12A ESC and a built-in serial ELRS receiver, delivering a complete, low-profile electronics package for micro digital builds.

Key features

• F405 Processor: Delivers additional hardware UARTs, eliminating the serial port limitations commonly found on micro F411 AIOs.
• Integrated Serial ELRS: Features an onboard ExpressLRS receiver connected via UART, allowing easy firmware updates independent of Betaflight releases.
• HD-Ready Architecture: Purpose-built for digital micro quads with straightforward connectivity for modern HD VTX units.
• 1-2S Power Delivery: Houses a 12A continuous ESC tailored for demanding micro motors on 1S or 2S LiPo packs.

Specifications

• MCU: STM32F405BGA
• Gyro: ICM42688
• Input Voltage: 1-2S LiPo
• Continuous Current: 12A
• Receiver: Onboard Serial ELRS (2.4GHz)
• Mounting Pattern: 25.5x25.5mm
• BEC: 5V 2A

This is an ideal foundation for 75mm to 85mm digital whoops or 2-inch micro freestyle frames that require the bandwidth and connectivity of an F405 MCU in a standard whoop footprint.
