This is a comparison of all currently (December 2019) available Nano sized video transmitters. To qualify for this list the video transmitter has to weigh less than 5g. Further it must be possible to adjust the video transmitters settings either via Smart Audio or IRC Tramp protocol. Those nano sized viedo transmitters are a great choice for your nano sized FPV camera.

Weight measurements are without antenna, if antenna is removable and without wires.

* Diamond means it is half the size of a classial whoop board and can be mountet above the FC with 3 screws (on the sides and on the back).
