General Description
VT-CC113L-433M is based on RF Transceiver CC113L of TI Chipcon,it’s a small size and ultra low power UHF wireless module. CC113L is a low cost true single chip UHF transmitter designed for very low power wireless applications. The circuit is mainly intended for the ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency bands at 315, 433, 868 and 915 MHz with data rate as high as 600Kbps. The module integrated many RF functions thus you can use it conveniently and reducing your development time.

Note:
1.The module transmission data rate will affect Transmission distance ,the higher the data rate , the closer the distance, and the lower the receiving sensitivity.
2.The supply voltage to the module will affect TX power, in the operating supply voltage range, the lower the voltage, the lower the TX power.
3.The module central frequency will change as the operating temperature change, use it under suggest temperature, the module can work well.
4.The antenna will strongly affect the communication distance, please select matched antenna and connect it correctly.
5.The module mount will affect the communication distance.
