USB/rf tranceiver wireless 869MHz

Converter USB to RF wireless data link for general use such as controlling devices from a computer or IoT applications. High performance transparent FSK RF data link module data transceiver with operating at 869 MHz. It features high output power, high sensitivity, long transmission distance and high communication data rate with auto set up for communication change and data receiving and transmission control. There is UART interface, it is easy to realize the wireless data transmission with only providing the UART data. It is flexible for the users to set the UART baud rate, frequency, output power, data rate, frequency deviation, receiving bandwidth etc parameters. It is your ideal choice for designing wireless data transmission products which can be widely used on wireless data transmission field.
