Product Description:

The Flywoo GOKU F405 HD 1S 5A AIO w/TXCO ELRS is a groundbreaking flight controller designed specifically for ultra-compact 1S HD drones, combining cutting-edge performance with unmatched portability.

Built around the STM32F405 BGA MCU, this all-in-one (AIO) board delivers superior computational power while maintaining an exceptionally lightweight design of 2.6g (excluding motor connectors ). Its cross-shaped PCB stacking ensures seamless compatibility with all 1S frame kits, making it ideal for pilots seeking precision, reliability, and adaptability in micro HD builds.

Highlights:

• When paired with the FLYWOO O4 1S 5V BEC module, it can achieve a minimum voltage of 2.6V.
• Integrated Serial ELRS 2.4GHz receiver (with TCXO crystal oscillator for superior precision and stability)
• STM32F405BGA aerospace-grade MCU (up to 68% faster processing vs. traditional F411 and 20% vs. G437)
• Equipped with ICM-42688P gyro and 8MB Betaflight Blackbox flash memory
• Ultra-compact, slim, cross-shaped PCB layout compatible with all popular 1S frames
• Specifically optimized for 1S HD drone setups, including Walksnail, HDZero, and DJI O4 systems
• Weighs just 2.6g without motor connectorsthe industry’s lightest 1S AIO solution
• Pre-soldered motor connector
