Product Description
The RFM12B is a legacy 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.
This has now been replaced with a new superior pin compatible module, the RFM69CW.
The new RFM69CW module offers better sensitivity (it can hear lower level signals) and much higher output (+13dBm vs 7dBm for 433MHz)
For details of using the new RFM69CW in exising RFM12B designs please see this design application note.
All major RF communication parameters are programmable and most of them can be dynamically set. The RFM69CW offers the unique advantage of programmable narrow-band and wide- band communication modes The RFM69CW is optimized for low power consumption while offering high RF output power and hannelized operation. Compliance ETSI and FCC regulations. In order to better use RFM69CW 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 RFM69CW modules, and enhance the application skills.
This is footprint compatible with the RFM12B see aspp note here
