RF Transceiver Module RFM69W 868MHZ
The RFM69W is a transceiver module capable of operation over a wide frequency range, including the 868 Mhz 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 RFM69W offers the unique advantage of programmable narrow-band and wide-band communication modes The RFM69W 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 RFM69W modules, this specification also involves a large number of the parameters and functions of its core chip RF69's, including those IC pins which are not led out. All of these can help customers gain a better understanding of the performance of RFM69W modules, and enhance the application skills.
