HopeRF's RFM31B are highly integrated, low cost,433/868/915MHZ wireless
ISM receiver module. The low receive sensitivity (–121dBm) 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.
