O4 vs O3

Right here’s a comparability desk between the DJI O4 Professional and DJI O3 Air Unit:

* DJI’s FPV techniques are recognized to have a tough vary restrict, which is expounded to software program constraints moderately than {hardware}. The precise arduous restrict for the DJI 04 Air Unit is at present unknown. The claimed most vary for the Avata 2 (which additionally makes use of the O4) is 13 km, however I think it can exceed that. For reference, the DJI Avata (V1) utilizing the O3 system is marketed at 10 km however has a real-world arduous cap of 23 km. Testing the true vary of the O4 system with the Avata 2 isn’t possible as a result of its battery gained’t final lengthy sufficient for such distances. We’ll have to attend for additional testing after its launch to substantiate.

DJI O4 Lite

The O4 Lite targets the micro FPV market, weighing below 10 grams and that includes a single-board design, which may make it a game-changer for micro quad builds akin to cinewhoops, toothpicks and even tiny whoops.

Racing Mode for Extremely-Low Latency

The brand new Racing Mode guarantees to scale back latency to as little as 15ms on the O4 Professional and 20ms on the O4 Lite when used with Goggles 3 (G3) and N3. This may very well be a game-changer for FPV racers, providing quicker response occasions that enhance management and cut back the possibility of desync throughout high-speed maneuvers. Nonetheless, Racing Mode is simply appropriate with Goggles 3 and N3; if you happen to’re utilizing Goggles 2 or Integra, chances are you’ll expertise barely increased latency.

Pinout and Wiring

The pinout and flight controller wiring are similar to the DJI O3 (VCC, GND, RX, TX, GND, SBUS). In extra to cable, the O4 additionally presents solder pads for direct soldering which is nice new for customized builds.

ND Filter

To realize cinematic footage, ND filter is a should. Learn to use ND filter on this tutorial: https://oscarliang.com/nd-filter-fpv/

Present Avata 2 ND filters will match the DJI O4 Professional digicam. The official ND filters from DJI may be of nice high quality, however they’re fairly costly. These filters can pop off and get misplaced throughout collisions, so choosing extra reasonably priced ND filters may be possibility for these on a funds.

SD Card Suggestions

SD playing cards should not included, so listed here are my suggestions: https://oscarliang.com/sd-cards-fpv/#GoPro-DJI-and-Different-HD-Cameras-4K-Movies. When capturing cinematic footage in dangerous areas, I all the time deliver a number of SD playing cards with me and swap them out after each flight. This minimizes the chance of dropping all my footage if the drone is misplaced.
