Ultra-Light 1S HD AIO for Digital Micro Builds
The Flywoo GOKU F405 HD 1S 5A ELRS AIO V2.0 is an all-in-one 1S FPV flight controller that combines an F405 FC, 5A 4-in-1 ESC, and built-in ELRS receiver on one ultra-compact board. Built specifically for DJI O4, Walksnail, and HDZero, it gives 1S HD micro drones a cleaner, lighter, and simpler electronics setup.
Highlights:
● On board FLYWOO O4 1S 5V BEC module, it can achieve a minimum voltage of 2.6V.
● Integrated Serial ELRS 2.4GHz receiver (with TCXO crystal oscillator for superior precision and stability)
● STM32F405BGA aerospace-grade MCU (up to 68% faster processing vs. traditional F411 and 20% vs. G437)
● STM32F405BGA aerospace-grade MCU (up to 68% faster processing vs. traditional F411 and 20% vs. G437)
● Ultra-compact, slim, cross-shaped PCB layout compatible with all popular 1S frames
● Specifically optimized for 1S HD drone setups, including Walksnail, HDZero, and DJI O4 systems
● Weighs just 2.6g without motor connectors—the industry's lightest 1S AIO solution
● Pre-soldered motor connector
ICM42688P-Independent Power Supply Architecture
With a 3.3V LDO regulator and power isolation, it reduces gyroscope interference, boosting lMU accuracy by 22% and enhancing flight performance for 1S systems.
Faster F405 Processing for Locked-In Flight Feel
Powered by an STM32F405BGA MCU (210 DMIPS @168MHz) and ICM42688P gyro, this 1S AIO delivers faster processing and cleaner gyro data than typical entry-level F411/G473 boards. The built-in 8MB blackbox also gives pilots the tuning data they need to dial in a sharper HD micro build.
User value: better stick feel, cleaner tuning, and more confidence when pushing a light 1S quad hard.
Built to Run DJI O4, Walksnail, and HDZero on 1S
This board is specifically optimized for 1S HD FPV builds, with an onboard 5V 3A BEC designed to provide stable power for digital video systems, including the DJI O4 Air Unit. Flywoo also highlights its low-voltage capability down to 2.6V, making it especially useful for tiny HD drones where stable VTX power matters.
User value: cleaner HD builds, fewer power issues, and more reliable video performance on 1S.
Integrated with Flywoo TCXO 2.4G ELRS, the temperature-compensated crystal oscillator enhances control stability and reliability, making drone component installation cleaner.
Plug-And-Play-One-Step Solution
Pre-soldered with JST1.25 motor connectors, allowing quick installation or replacement of motors without soldering. Enjoy effortless maintenance and a seamless, minimalist experience.
2.6g Ultra-Light for Modern 1S Frames
At just 2.6g without motor connectors, the GOKU F405 HD 1S 5A AIO V2.0 is one of the lightest options in its class. Its slim, cross-style 30.5 × 30.5mm layout with 25.5 × 25.5mm mounting makes it easy to fit into many popular 1S HD whoop and micro drone frames.
User value: lower build weight, easier frame fitment, and more room to keep a tiny HD quad efficient and responsive.
