Product Description

The RFM69HW is a low cost, long range, highly integrated, 433MHz, 868MHz & 915MHz RF wireless ISM transceiver module (frequency depends on the product selected). The high receiver sensitivity (–121dBm @ 1.2kbps) coupled with industry leading +20dBm output power ensures extended range and improved link performance. These modules can communicate over many, many km’s depending on the data rate and RF environment. All major RF communication parameters are programmable and most of them can be dynamically set.  The  RFM69HW offers the unique advantage of programmable narrow-band and wide-band communication modes without the need to modify external components. The RFM69HW 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 wide operating voltage range of 1.8–3.6 V and low current consumption makes the RFM69HW an ideal solution for battery powered applications.

Communication with the RFM69HW module is via a standard 4-wire SPI interface. Three configurable general purpose I/Os are also available, the use of which can be tailored for the needs of your project or solution. The RFM69HW also incorporates a range of other features, including an 8-bit ADC, temperature sensor, RX and TX FIFOs, and low-battery detection. A datasheet for this product is available below (manufacturer provided)

The module comes in a 16-pin, 16 x 16mm, SMD package, with pins spaced by 2mm.
