Whadda RFM69HCW radio module for Arduino

The RFM69HCW module is a cost-effective and versatile radio module. It allows you to send text or binary data between two or hundreds of modules. It is perfect for building low-cost wireless short-range networks for home and building automation, sensor networks, automated meter readings, wireless alarm and security systems, industrial monitoring and control, as well as many other applications. The RFM69HCW transceiver module operates over a wide frequency range, including the license-free ISM frequency bands (Industry Scientific and Medical) at 315, 433, 868, and 915 MHz. All important RF communication parameters are programmable, and most can be dynamically adjusted. The RFM69HCW is optimized for low power consumption while providing high RF output power and channelized operation. This VMA214 RFM69HCW Radio Shield connects the RFM69HCW module to the appropriate pins on the Arduino. Using the RF69 library, you can send and receive messages over the standard 4-wire SPI interface. The library includes command structures for setting up simple unaddressed point-to-point communication to fully addressed networks of clients and routers. The frequency can be set with an accuracy of 61 Hz to any frequency from 240.0 MHz to 960.0 MHz. The shield features integrated power regulation and level shifting, an external antenna via the I-Pex connector, and additional jumpers for configuring the interface and digital communication pins on the Arduino.
