General Description
VT-CC1121-433M is based on RF Transceiver CC1121 of TI Chipcon,it's a small size and ultra low power UHF wireless module. CC1121 is fully integrated single-chip radio transceiver designed for high performance at very low power and low voltage operation in cost effective wireless systems. The circuit is mainly intended for the ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency bands at 164-192 MHz, 410-480 MHz and 820-960 MHz. The MAX RF output power can be set as high as +15dBm, with data rate as high as 200Kbps. The module integrated many RF functions thus you can use it conveniently and reducing your development time.
