This module is an UHF 200mw power transmitter. It has one video and one audio inputs. It is powered in a range from 3.3v to 5v. It has a litthe antenna cord.
The use of this module is pretty simple. You must to have a source of video and sound, i.e. from a the scart input/output of your TV or TDT. This can be easily obtained usind an Scart to RCA connector, that have a input/output switch in it, choose Output and go.
Yo need also a two line RCA male to male cable. To make the module more affordable to the connections, is better to solder this module to a PCB and attach to it two RCA female connectors, one power female connector, and an antenna female connector.
I used two in line diode to reduce voltage from an USB charger, that feeds the device.
The final project is in this youtube video, working:
