FAQs
Yes, please check the blow video link at the youtube.
- This model support customizing the IP mesh function. There are three versions: 3km, 10km, and 50km according to build different the power amplifier.
- Normal default full duplex link module support relay, you should buy at least three or more units. One unit is the transmitter, one unit as the receiver, and the other unit can put the middle between the transmitter and receiver as the relay/repeater/extender.
The maximum RF transmission power of this two-way data video link module is 25±2 dBm, We also provides power amplifier to increase the RF Power to 2W/5W/10W. Below diagram shows how to add power amplifier outside of two-way digital data video link module.
Where is the IIC_SCL pin on the module?
Yes, Please check the below link product, which is used the wireless video data audio two-way link module to assemble, just plus the Power ampleifier and encloser and accessory.

There was no function to query the temperature of the module.
- Sure. It is ok.
- The Moningcore CX6600 is only an electronics module, you need to develop a peripheral circuit to support it, like power and ethernet and data Input Outport. And you also need to hire a software engineer to develop the firmware and UI for you.
- As a trial sample, it is better that you can buy our complete products to test. After you test and use them, the quality is satisfied, then try to buy the module or parts to develop it by yourself. You can copy our design and improve it to be an excellent product.
- After all, this is a radio transmission product, and any improper operation may interfere with the signal, resulting in shorter transmission distances.
- Sure. support.
- There is no optional frequency band of 2.4G modification on the web page, you need to send AT commands to modify or enter the Morningcore web page to modify.
- Sure. 58*64*13mm.
- If you need further dimension, please download our CAD file at the below link. (maybe you need AutoCAD or other CAD software to open it)
