This package consists of two half-duplex wireless data transceiver modules and each module is highly integrated with an MCU and a powerful RF chip. These modules boast features such as selectable channels, ultra long transmission distance (1000 meters) and abundant interface options (UART/TTL,RS-485&RS-232). The software application ("RF-Magic") is offered for free so that users can modify the settings of the module. This is a popular module thanks to its ease of use, slim size and wide power supply range.
