Description

If you've ever wanted to add HD FPV to an RC car, boat, plane or anything else without a flight controller, the O3 Armer is exactly what you need!

The DJI O3 video system will not output its full power unless there is an 'armed' signal sent to it, like you'd get from a flight controller. The O3 Armer sends this 'armed' signal after being powered on for ~20 seconds, automatically.

Just plug in your O3 Air Unit with its stock cable, power the O3 Armer from a 2S-4S LiPo and you're set. There is also a JST-XH connector for a 5V fan to keep your O3 cool, and an optional solder pad which accepts a PWM input, allowing you to turn the O3 Air Unit on/off and toggle low/high power mode.

Specifications

Input Voltage	7-17V DC
Battery Connection	XT30
Air Unit Connection	6-pin JST-SH
Fan/5V Connection	2-pin JST-XH

Awesome O3 air unit armer. I use it without the fan plug as I need 8.5v to cool the air unit plus removing the plug made getting heat shrink on easier. Only dislike is it doesn’t work unless you get the green flashing light. Every other power up is a dud. Not sure why it’s designed this way. But way better than the Arduino board I used previously.

Revolutionary products

Mr. Rains has brought a new level of innovation to FPV by combining a new product for different hobbies.

Great device

Does exactly what i needed 😁 works great

No Flight Controller Needed !!!

I'm usning one of these on a airplane that I just did not want the hassel of putting a flight controller in. I also wanted to keep the weight down.

I'm using a CADDX Vista air unit with older Goggles V2. It works great with the O3 Armer.
