Keyestudio FSK Wireless Shield RFM69HCW 868mhz(Black and Eco

Keyestudio FSK wireless shield is long range transceiver based on Arduino open source platform . It can send data and reach extremely long ranges at low data-rates, featuring high interference immunity and low current consumption in communication.
In addition, it can be applied to multiple wireless sensors and network applications, such as irrigation systems, smart metering, smart cities, smart phone detection, building automation, and so on.
It also supports FSK mode like WMBus and IEEE802.15.4g system. Simultaneously, this board delivers exceptional phase noise, selectivity, receiver linearity and IIP3 for significantly lower current consumption than competing devices.
