FPV Analog Video Transmitter CVBS audio video module sender 400-900MHz UHF vcan1904

FPV Analog Video Transmitter CVBS audio video module sender 400-900MHz UHF vcan1904

Umumiy nuqtai

This module belongs to UHF Radio communication equipment in the frequency band, which can transmit audio and video within a limited range. Designed for low power consumption, integrated VCO, PLL, and AM broadband video demodulation, The audio carrier frequency makes the module smaller; it adopts a small single-board package, which is convenient for users to miniaturize applications.

The application of this module only needs to simply connect the power supply, audio cable, and video cable, and connect the antenna to use a variety of electronic equipment terminals that support analog TV reception, mobil telefonlar, shu jumladan, TVs, laptops, MP4, and digital photos.
