Flywoo GOKU F405 HD 1S 5A ELRS AIO V2

The Flywoo GOKU F405 HD 1S 5A AIO V2 was specifically developed for ultra-micro 1S HD drones and builds on the proven strengths of the V1 version with targeted technical improvements.

At its core is the STM32F405 BGA microcontroller, combining high-performance processing at 168 MHz with low power consumption, all at a weight of just 2.6 g. The innovative cross-shaped design is compatible with all 1S frame kits.

One of the key V2 upgrades is the integrated Flywoo 1S O4 5V BEC, which supports a minimum operating voltage of 2.6 V, making it ideally suited for use with the DJI O4 VTX. Weight, performance, and form factor are identical to the V1 version, ensuring a seamless and familiar user experience.

In addition, an ELRS 2.4 GHz receiver and a TCXO (temperature-compensated crystal oscillator) are integrated, providing stable, low-latency signal transmission. The built-in ICM42688P gyroscope and the 8 MB Betaflight Blackbox enable detailed flight data recording and analysis. As a result, this AIO board is equally suitable for professionals and beginners building ultra-micro 1S HD drones.

Features

• Integrated FLYWOO O4 1S 5V BEC module with a minimum operating voltage of 2.6 V
• Integrated serial ELRS 2.4 GHz receiver with TCXO crystal oscillator for maximum precision and signal stability
