The RFM69HCW module is a cost-effective and versatile radio module. You can use it to send text or binary data between two or a hundred modules. ideal for building low-cost, short-term WLAN networks for home & building automation, sensor networks, automated meter measurements, wireless alarm and security systems, industrial monitoring and control, and many other applications!The RFM69HCW transceiver module operates over a wide frequency range, including the online frequency bands of 315, 433, 868 and 915 MHz. All large RF communication parameters are programmable and most can be set dynamically. The RFM69HCW is optimized for low power consumption, offering high RF output power and conductive operation.The VMA348 RFM69HCW transceiver breakout board produces all the pins and the antenna connection. Each module has pre-soldered headers, a 3.3V voltage regulator, and a step switch that can handle 3-5V DC power and logic so you can use it with 3V or 5V devices. You need to solder a small pi
