Note: The O4 lite can handle a max voltage of 1-3S. When using a 4S battery, an extra 5V BEC is needed.

The Flywoo F405 NANO has been completely upgraded! We have further minimized and integrated the FC layout based on the original design. The new Flywoo GOKU GN405 Nano FC V3 w ELRS 2.4g is compact and features a USB-C universal port that is compatible with current mainstream data cables. It also supports the DJI O3 interface, allowing compatibility with high-quality digital transmission modules. Additionally, it has a complete set of six UART ports. Importantly, this flight controller is equipped with a TCXO ELRS high-precision receiver, making it an ideal solution for space-saving in micro drones. This flight controller is compatible with both QUAD and HEX drones, and users can switch between different ESC models. The latest three ESC models include: the 20A (QUAD) plug-and-play ESC, the 20A (HEX) plug-and-play ESC, and the high-performance 35A (QUAD) ESC. These options meet your compatibility needs for different drones, ensuring you have fun during your flights!
