Pro-Grade O4 Digital FPV Transmission Module
Introduction
Elevate your FPV experience with the O4 Digital FPV Transmission Module—your all-in-one solution for seamless connectivity, ultra-low latency, and pro-level imaging. Designed to integrate flawlessly with the DJI ecosystem, this compact, lightweight module delivers rock-solid performance for both casual pilots and competitive racers, making every flight smoother, more immersive, and easier to capture.
Key Features
1. Seamless DJI Ecosystem Compatibility
Plug-and-play with DJI Goggles 2 (2022)/Integra (2023)/3 (G3, 2024)/N3 (2024) and DJI FPV Remote Controller 2 (RC2, 2023)/3 (RC3, 2024). No complicated pairing or extra adapters—connect in seconds and take flight immediately, perfect for both beginners and seasoned pilots.
2. O4 Digital FPV Transmission: FHD, Low Latency & Anti-Interference
Experience industry-leading O4 digital transmission with intelligent frequency hopping, ensuring a stable signal link indoors, outdoors, and in crowded environments. Supports up to 8 synchronized aircraft in Race Mode, making it ideal for multi-pilot competitions. Enjoy ultra-responsive control with 20ms low latency (Racing Mode with DJI Goggles 3) and an impressive 10km max transmission range (FCC).
3. Pro-Grade Imaging & Stabilization
Equipped with a 1/2-inch CMOS sensor, capture stunning 4K/60fps video and smooth 1080p/100fps real-time live view via H.265 encoding—preserving every detail of your flight. RockSteady 3.0+ EIS eliminates shake for cinematic footage, and Gyroflow support (when stabilization is off) offers professional-level post-processing flexibility.
4. Customizable OSD for Personalized Control
Take full control with CanvasMode and Betaflight OSD—personalize real-time data overlays (RSSI, battery level, flight stats, etc.) to match your flying style and needs. Full-screen control ensures you stay informed without distracting from the immersive view.
5. Ultra-Lightweight & Compact Design
Weighing only 8.2g (with camera module) or 5.1g (without), with a 20x20mm VTX mounting pattern, this module is designed for drone frames ≤2-inch. It adds negligible payload, preserving drone agilityy and flight efficiency while fitting diverse DIY build requirements.
6. Built-in 23GB High-Capacity Storage
