RFM69HCW RFM69HCW ISM TRANSCEIVER MODULE v1.1 GENERAL DESCRIPTION TAL ND The RFM69HCW is a transceiver module capable of operation over a wide frequency range, including the 315,433,868 and 915MHz license-free ISM (Industry Scientific and Medical) frequency bands. All major RF communication parameters are programmable and most of them can be dynamically set. The RFM69HCW offers the unique advantage of programmable narrow-band and wide- band communication modes. The RFM69HCW is optimized for low power consumption while offering high RF output power and channelized operation. Compliance ETSI and FCC regulations. RFM69HCW In order to better use RFM69HCW modules, this specification also involves a large number of the parameters and functions of its core chip RF69H s,including those IC pins which are not leaded out. All of these can help customers gain a better understanding of the performance of RFM69HCW modules, and enhance the application skills.
