Generic 45 Multi-Function 2.4GHz RF Switching Module w/ PCB Antenna

No, this module is a standalone transceiver with embedded control logic. It handles ID learning, frequency hopping, and command processing internally, allowing it to function directly from switch inputs or serial data without any external microcontroller, simplifying your wireless control system design.

The ID learning process is typically initiated by placing both transmitter and receiver into a binding mode, often via a button press or specific power-up sequence. Once in this mode, the modules exchange and store a unique ID using their built-in logic. This paired ID is retained in non-volatile memory, ensuring the link persists after a power cycle.

The module features ultra-low power consumption with an idle current of only 20 microamps. It operates from a wide voltage range of 2.0 to 3.6 volts DC, making it ideal for direct powering from two AA/AAA batteries or a single Li-ion cell, supporting long-term deployment in battery-powered remote controls and sensors.

The specified 1000-meter range is a theoretical line-of-sight maximum under ideal conditions with +20dBm transmit power. Real-world range is significantly affected by obstacles, interference, and antenna orientation. For reliable operation, expect effective distances of 100-300 meters in urban or indoor environments using the integrated PCB antenna.

For switch control, connect your physical switch contacts to the designated input pins on the module's header. For serial data transmission, connect your host device's TX/RX lines to the module's serial pins and configure the communication baud rate (e.g., 9600 bps) via AT commands or pre-configured firmware, as per the module's datasheet.
