Flywoo GOKU F405 HD 1S 5A ELRS AIO 25.5×25.5mm For Firefly16 Firefly18 DJI O4 Walksnail HDZero FPV Racing Drone FW4769

Flywoo GOKU F405 HD 1S 5A ELRS AIO 25.5×25.5mm For Firefly16 Firefly18 DJI O4 Walksnail HDZero FPV Racing Drone FW4769

Description:
This  ​​Flywoo GOKU F405 HD 1S 5A AIO V2 is tailored for ultra-micro 1S HD drones, building on V1’s strengths with key upgrades.

At its core is the STM32F405 BGA micro MCU, delivering 168MHz high-frequency performance, low power consumption, and a mere 2.6g weight. Its innovative cross-shaped design fits all 1S frame kits.

Key V2 upgrades: On-board Flywoo 1S O4 5V BEC supports a minimum operating voltage of 2.6V when paired with DJI O4 VTX. It matches V1 exactly in weight, performance, and shape for a seamless classic experience.

Also integrated are an ELRS 2.4GHz receiver and TXCO (Temperature-Compensated Crystal Oscillator) for stable, low-latency signals. On-board ICM42688p gyro and 8MB Betaflight black box enable flight data recording and analysis—making it an ideal choice for both pros and beginners building ultra-micro 1S HD drones.

Highlights:
– On board 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 connectors—the industry's lightest 1S AIO solution
– Pre-soldered motor connector
