General Description

Description

VT-CC2500PA-M1 is based on RF transceiver CC2500 of TI Chipcon. CC2500 is a low-cost 2.4 GHz

transceiver 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 PA CC2591 to

make the max RF output power up to +20dBm. There is an inverted F antenna on the module. So you can use the

module conveniently and reducing your development time.

Features
