General Description

VT-CC2500-M1 is based on RF transceiver CC2500 of TI Chipcon,it’s a small size and low power consumption module. CC2500 is a low-cost 2.4 GHz transceiver designed for designed for very low power wireless applications. The circuit is intended for the 2400-2483.5 MHz ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency band. The MAX RF output power can be set as high as +1dBm, with data rate as high as 500Kbps. The module integrated many RF functions thus you can use it conveniently and reducing your development time.

General Characteristics

Test operating conditions:Ta=25°C,VCC=3.3V if nothing else stated.

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.
