Product Description

COFDM Digital Receiver Module With Dual Antenna Diversity Reception Receiving Sensitivity -106dbm


C204 COFDM Digital receiver module can receive audio and video signals from different band of frequency,support HDMI and CVBS external display interface,USB external storage,To achieve the audio and video transmission between the transmitter and the LinkAV-C204 receiver module only 114.4x91x32.8 lightweight.

The use of advanced diversity reception technology,overcoming the difficulties of multipath reflection and blocking in image transmission under analog and conventional modulation techniques.High-quality standard-definition images can be transmitted in real-time under high-speed motion or non-line-of-sight conditions,Particularly suitable for use in complex environments.audio and video decoding using H.264 standard, with a clear picture quality, bright colors, smooth image characteristics.


1,TF Card:For TF card installation(128G,FAT32 File System),For video storage.

2,OSD data transmission: For datas output from UAV or other(UART TTL level asynchronous serial port transmission channel),OSD UART Baud rate is 115200.

3,Frequency Modulator:Decimal TTL level( Connect with frequency and power adjust board),Baud rate 9600.We have Frequency Modulator for frequency and bandwidth Serial port setup command please turn to our sales for another document.

4,Indicator:Red is power indicator,down green is working light,up is signal indicator,The faster the flashing,the larger the datas.

5,REC:Recording Button for video storage.
