DJI O4 Air Unit Leaked: Standard and Pro Versions Revealed in Technical Documents

A leaked technical document has revealed DJI’s plans for two versions of their next-generation FPV system – the DJI O4 Air Unit and DJI O4 Air Unit Pro. The documents, which appear to be design schematics in a manual, showcase distinct differences between the standard and professional models and were shared by OsitaLV on X.

Two-Tier Approach to Digital FPV

The leaked schematics show that DJI is taking a dual-product approach with their next digital FPV system. The standard O4 Air Unit features a simpler design with a single-piece camera unit, while the Pro version boasts what appears to be a more robust camera module, enhanced cooling capabilities, and a stronger dual antenna setup.

Technical Design Details

The technical drawings reveal several key design elements:

• Both units feature a main processing board connected to a camera module
• The Pro version includes what appears to be additional cooling infrastructure
• Connection interfaces appear to be standardized across both models
• The base unit shows a 6-pin connection system, suggesting compatibility with existing DJI ecosystem products

Building on O3’s Foundation

These developments follow DJI’s current O3 Air Unit, which already offers impressive specifications including:

• 1/1.7-inch image sensor
• 10km transmission range
• 1080p/100fps transmission capabilities
• 30ms latency digital video feed

What Improvements Could the O4 Air Unit Bring Over O3?

Based on the provided documentation and current O3 specifications, let’s analyze the potential upgrades we might see in the O4 Air Units.

Expected Camera Improvements

The technical documents suggest possible camera enhancements, particularly in the Pro version, which shows a more substantial camera housing. This could indicate:

• Potential upgrade from the O3’s 1/1.7-inch sensor to a larger 1/1.3″ sensor
• Improved low-light performance
• Enhanced image quality and dynamic range

Thermal Management Solutions

A standout feature in the leaked schematics, especially for the Pro version, appears to be improved cooling design:

• More substantial heatsink architecture visible in the Pro unit
• Enhanced thermal management infrastructure
• Potential solution to the O3’s known overheating issues

Dual Product Strategy

The introduction of two distinct models could address different user needs:

• Standard O4 Air Unit: Likely focused on lightweight applications and racing
• O4 Air Unit Pro: Geared toward professional cinematography and demanding applications

DroneXL’s Take on the DJI O4 Air Unit Pro

The leaked O4 Air Unit designs show promising improvements over the O3 system. The dual-product approach aligns with trends we’ve seen in drone technology, where manufacturers offer tiered solutions for different user needs. The focus on thermal management, particularly in the Pro version, addresses one of the main criticisms of the DJI O3 system.
