DJI O3

DJI O3 Digital FPV System

Essentially O3 is the DJI Digital FPV system with an additional processor.  The main RF chipset and SOC is the same as the Digital FPV system but DJI added in the E3T chipset.   

Basically all Ocusync 2 devices like the DJI Digital FPV system and the DJI Mavic ect all run the wireless link from the P1 chipset, It handles both the Linux RTOS for video processing and encoding as well as the deeper LTE based RF Modems all in one, it’s a custom Asic wit unknown manufactures but is based on Leadcore and Artosyn. 

In O3 DJI use the same P1 chipset but added the far more powerful E3T processor that handles the “heavy lifting” as such, it does the main RTOS, video encoding and processing then the P1acts as an rf modem. As a result of this they DJI have been able to improve overall Ocusync performance, image quality and add H265 encoding when used with the Goggles 2.

However the very basics are O3 is based on the current DJI Digital FPV with the extra processing.
