The RFM69 is the successor to the ever popular RFM12 from HopeRF. It is a highly integrated RF transceiver capable of operation over a wide frequency range, including the 433, 868 and 915 MHz license-free ISM (Industry Scientific and Medical) frequency bands. Its highly integrated architecture allows for a minimum of external components whilst maintaining maximum design flexibility. All major RF communication parameters are programmable and most of them can be dynamically set. The RFM69 offers the unique advantage of programmable narrow-band and wide-band communication modes without the need to modify external components. The RFM69 is optimized for low power consumption while offering high RF output power and channelized operation. TrueRF technology enables a low-cost external component count (elimination of the SAW filter) whilst still satisfying ETSI and FCC regulations. The module comes in a 16-pin, 16 x 16mm, SMD package, with pins spaced by 2mm.
