RFM69W
RF M69W I SM T R ANS C EI VE R MO DUL E V1.2
GENERAL DESCRIPTION
The RFM69W 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 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 leaded out. All of these can help customers
gain a better understanding of the performance of RFM69W
modules, and enhance the application skills.
