This is a comparison of all currently (April 2021) available AIO cameras. To qualify for this list the camera has to come bundled with a video transmitter and they together have to weigh less than 5g. Further it must be possible to adjust the video-transmitters settings either via Smart Audio or IRC Tramp protocol.

This AIO systems are the perfect choice for 1S builds were every gram counts. They are also a good choice for toothpick sized quadcopters since camera and transmitter can easily be mounted on top of the stack with a single mount.

Due to advances in flight controllers and size of cameras and video transmitters the AIO form factor is getting less and less relevant. Nowadays you can get a dedicated Nano Cam and Nano vidoe transmitter for almost the same money without sacrificing too much additional weight, or even chosing a flight-controller with integrated video transmitter.
