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
