The RFM31 is low cost ISM receiver module and offers advanced radio features including continuous frequency coverage from

240–960 MHz , The extremely low receive sensitivity (–118 dBm) ensures extended range and improved link 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 lower-cost system MCUs. An

integrated temperature sensor, general purpose ADC, power-on-reset (POR), and GPIOs further reduce overall system cost

and size.

The RFM31‘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. This digital architecture simplifies system

design while allowing for the use of lower-end MCUs.
