Product description
RX-4MM3/F is a superheterodyne RF receiver module for receiving AM/ASK modulated digital data in the 433.92 MHz band. It is designed for high selectivity and high sensitivity, providing good noise immunity even in environments with electrical noise, such as from brushed motors. The module is pin-compatible with other Aurel OOK receivers and is suitable for applications such as gate control, actuators, shutter control, and industrial systems.
The internal superheterodyne architecture with IF filter and AGC provides stable reception and reliable data detection. Data is delivered as a digital signal via Data Out, and RSSI is available for signal monitoring or testing.
