434MHz and 915MHz Wireless Transceivers

SparkFun Electronics

This is the 434MHz and 915MHz base RFM69HCW Wireless Transceivers that is found on the RFM69 Breakout. The RFM69HCW is an inexpensive and versatile radio module that operates in the unlicensed ISM (Industry, Science and Medicine) band, a set of frequencies set aside for low power, short-range, license-free radios. It is perfect for building inexpensive short-range wireless networks of sensors and actuators for home automation, citizen science and more. The RFM69HCW module operates on the 434MHz and 915MHz frequency and is capable of transmitting at up to 100mW and up to 300kbps, but you can change both of those values to fit your application. For example, you can maximize range by increasing the transmit power and reducing the data rate, or you can reduce both for short-range sensor networks that sip battery power. At full power and with simple wire antennas, that can get messages from one side of a large office building to the other through numerous internal walls.
