Product Introduction
The image transmission kit consists of a sky end and a ground end, using the new generation of wireless transmission and image encoding technology.
The Sky end is composed of an image sensor and an image transmission chip, with built-in dual antennas and technologies such as automatic power adjustment and automatic frequency hopping, making it have stronger anti-interference performance.
On the ground end, multiple image transmission and display methods are provided, allowing users to freely use HDMI and DP displays. And reserve MIPI interface for direct drive 4-5 inch screen (customized), allowing Shuangfei to operate to the end.
The image transmission kit is widely used in the fields of unmanned aerial vehicles (FPVs, fixed wing, cruise aircraft), robots, and more.
There are two specifications for the image transmission kit: the ultra long distance Pro version and the regular version (please refer to the parameter table for differences)
