An on-board video camera can be used to record aerial video and/or directly transmit the live video back to the pilot, which is called FPV (“First Person View”).
This camera comes with different names:
It is a lightweight camera that delivers a good quality 720p video recording and is really tiny in size.
The vendor offers an analog output cable, which allows to see the live view from the camera Live View cable.
What is not so optimal is the limited recording time with the inbuilt 1S Lipo of around 40 (tested) - 50 (advertised) recording time. You will need to make sure it is fully charged before each time you go flying.
Follow these steps so you can power your cam directly from a free servo connection on your PX4IO board.
