Description
HopeRFs RFM31B are highly integrated, low cost,433/868/915MHZ wireless ISM receiver module. The low receive sensitivity (–121dBm) ensures and support for frequency hopping can be used to further extend range and extendedrange and improved link performance.Built-in antenna diversity enhance performance.
