The The MikroElektronika's ISM RX 3 Click is a compact add on board that contains a Sub GHz RF receiver. This board features the MAX41470, a high performance, low power receiver ideal for amplitude shift keyed ASK and frequency shift keyed FSK data from Analog Devices. It can be configured for three sub 1GHz bands using an on board 16MHz crystal: 287MHz to 320MHz, 425MHz to 480MHz, and 860MHz to 960MHz, fully programmable through an SPI interface. The receiver has excellent RF sensitivity and long range, allows input signals up to 0dBm of power at the RF input, and features a fully programmable, self polling duty cycling mode with preamble detection and interrupt output to wake up an external MCU. This Click board is suitable for cost- and power-sensitive applications, such as home automation and security, building access control, remote keyless entry, garage or gate doors control, and similar applications.
