Flywoo GOKU F405 HD 1S 12A AIO Flight Controller, Plug & Play for DJI O4/O4 Pro

Product description

The Flywoo GOKU F405 HD 1S 12A AIO is a high-performance all-in-one flight controller for modern 1S HD FPV drones and was developed specifically for the DJI O4 and DJI O4 Pro Air Unit. As one of the first 1S AIO controllers with a direct plug-and-play connection for the O4 series, it enables a particularly simple setup without complicated soldering work. With its powerful STM32F405BGA processor, the precise ICM42688P gyroscope, integrated 12A 4-in-1 ESC, dual BECs, and an integrated ELRS 2.4 GHz receiver with TCXO, the controller is designed for demanding Tiny Whoop, Toothpick, and Micro-HD builds.

Unlike traditional 1S AIO boards with 5A ESCs, the GOKU F405 features a 12A continuous current rating (15A peak), providing ample power reserves for motors ranging from 0802 to 1303. The integrated 5V/3A and 9V/2A BECs reliably supply both the flight controller and the DJI O4 Air Unit with stable voltage—even during heavy load changes. The specially developed plug-and-play connector allows for a direct connection to the DJI O4 or O4 Pro without additional soldering.

The integrated Flywoo TCXO ELRS 2.4 GHz UART receiver provides a particularly stable radio connection. The temperature-compensated crystal oscillator (TCXO) minimizes frequency deviations and ensures reliable signal transmission even under varying temperatures. In addition, the flight controller supports direct connection to a GOKU GM10 Nano GPS module or an external OpenLager Blackbox module, making it easy to implement long-range or GPS rescue projects.

Thanks to the pre-installed JST 1.25 motor connectors, the A30 battery connector, and the modern USB-C port, setup is particularly easy. The controller supports both Betaflight and INAV and is suitable for Tiny Whoops starting at 40 mm up to 3-inch toothpick drones.
