The RFM64W is a low-cost 433MHz ISM-band transceiver module. The RFM64W is optimized for very low power consumption. All major RF communication parameters are programmable and most of them may be dynamically set. In order to better use RFM64W modules, this specification also involves a large number of the parameters and functions of its RF64 core chip, including those IC pins which are not leaded out. All of these can help customers gain a better understanding of the performance of RFM64W modules.
