Description
Specifications
As the industry’s first 1S AIO (All-in-One) flight controller specifically optimized for the DJI O4 and O4 Pro high-definition digital systems, the GOKU F405 HD sets a new standard for ultralight FPV performance. Built on a powerful STM32F405 MCU and a precision ICM42688P IMU, it provides the processing headroom and gyro stability required for cinematic 1S builds.
Unlike standard 5A boards, this AIO integrates a robust 12A continuous (15A peak) ESC and dual high-efficiency BECs (9V/2A and 5V/3A), ensuring your O4 Air Unit receives consistent power even during aggressive maneuvers. Whether you are building a 40mm Tiny Whoop or a 3-inch long-range toothpick, its plug-and-play design and TCXO ELRS 2.4G receiver offer a seamless, interference-free connection for the most demanding pilots.
Highlights:
- Wide Compatibility: Works with 40mm-3inch propeller frames and 0802-1303 micro motors
- Dual BEC : Built-in 9V/5V dual BEC, providing independent and stable voltage
- Powerful ESCs: 12A high-spec ESCs optimized for 1S systems, delivering smooth power and fast response
- Serial ELRS: Integrated serial ELRS 2.4GHz receiver (built-in TCXO crystal oscillator)
- Solder-Free Assembly: Solder-free motor socket design simplifies the assembly process
- Convenient Interface: Equipped with USB-C port
- Powerful MCU : STM32F405BGA aerospace-grade MCU (up to 68% faster processing vs. traditional F411 and 20% vs. G437)
- Plug and Pay : Supports direct plug-in of O4/O4PRO , no soldering required, stable signal
- External Black Box or GPS: Supports direact plug in of GOKU GM10 Nano V3 GPS or Flywoo 0.4g OpenLager Nano module with 512MB capacity
