Flywoo GOKU F405 HD 1S 5A ELRS AIO V2.0 Flight Controller/ESC for DJI O4, Walksnail, HDZero

Overview

The Flywoo GOKU F405 HD 1S 5A ELRS AIO V2.0 is a 1S all-in-one flight controller and 4-in-1 ESC for ultra-micro HD drone builds, optimized for DJI O4, Walksnail, and HDZero setups. It features an STM32F405BGA MCU (168MHz; 210 DMIPS @ 168MHz stated), integrated Serial ELRS 2.4GHz receiver with TCXO, ICM42688P gyro, and onboard 8MB/8M blackbox.

Key Features

• Ultra-mini 1S HD camera compatible design; cross-shaped PCB layout designed to fit 1S frames
• Low weight: 2.6g (stated); “Extreme weight of 2.6g”
• Onboard Flywoo O4 1S 5V BEC; minimum operating voltage 2.6V (stated) when paired with DJI O4 VTX; BEC output 5V 3.0A MAX (supports DJI O4 Air Unit)
• Integrated Serial ELRS 2.4GHz receiver with TCXO for stable, low-latency signal
• ICM42688P gyro with independent power supply architecture (3.3V LDO regulator + power isolation); IMU accuracy +22% (stated)
• F405BGA main control: processing +30% vs. F411/G473 (stated)
• Plug-and-play motor wiring: pre-soldered JST1.25 motor connectors (no motor soldering required)

Details

The GOKU F405 HD 1S 5A AIO ELRS V2 keeps wiring organized with clearly labeled pads, a built-in antenna mount, and a USB-C port for quick setup.

The ICM42688P IMU uses a 3.3V LDO regulator with power isolation to help reduce gyroscope interference in 1S builds.

The F405BGA main control is built around an STM32F405 chip with a 168MHz clock speed.

The GOKU F405 HD AIO integrates a 2.4GHz ELRS receiver with TCXO crystal oscillator compensation for a cleaner, all-in-one build.

Pre-soldered JST1.25 motor connectors let you swap or install motors quickly without soldering.

The Flywoo GOKU F405 HD 1S AIO board keeps weight down at 2.6g for compact HD micro builds.

The GOKU F405 HD AIO supports DJI O4 image transmission, with a built-in 1S 5V BEC to power the O4 VTX under full load.

The Flywoo GOKU F405 HD 1S AIO V2 wiring layout labels 5V/GND, TX/RX, SBUS, and CH1/CH2 pads for cleaner, more reliable hookups.

Clearly labeled UART pads (TX/RX), SBUS, and power/ground points help make wiring an HD build cleaner and easier to troubleshoot.
