RFM69HC Wireless Transmitter Module 915MHZ Frequency

The RFM69HC 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 RFM69HC offers the unique advantage of programmable narrow-band and wide- band communication modes. The RFM69HC is optimized for low power consumption while offering high RF output power and channelized operation. Compliance ETSI and FCC regulations. In order to better use RFM69HC 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 RFM69HC modules, and enhance the application skills.

This product is 915MHz RFM69HC RF transceiver.
