Features

The RFM31B is a highly integrated, low cost, 433/868/915MHz wireless ISM receiver module. The low receive sensitivity ensures extended range and improved link performance. Built-in antenna diversity and support for frequency hopping can be used to further extend range and enhance performance.

Additional system features such as an automatic wake-up timer, low battery detector, 64 byte RX FIFO, automatic packet handling, and preamble detection reduce overall current consumption and allow the use of a lower-cost system MCU. An integrated temperature sensor, general purpose ADC, power-on-reset (POR), and GPIOs further reduce overall system cost and size.

The RFM31B's digital receive architecture features a high-performance ADC and DSP based modem which performs demodulation, filtering, and packet handling for increased flexibility and performance.

An easy-to-use calculator is provided to quickly configure the radio settings, simplifying customer's system design and reducing time to market.
