Description

The 43 Wireless 2.4G Switching Module is a compact, self-contained RF transmitter engineered for reliable wireless remote control. It operates across the 2.4GHz ISM band (2400–2483.5 MHz) with a maximum transmit power of +5 dBm, providing a robust link for command and control signals. Its integrated architecture includes ID pairing, frequency hopping, and non-volatile memory, ensuring secure, interference-resistant operation and state retention after power cycles.

Designed for ease of integration, the module eliminates the need for an external microcontroller, accepting direct serial data or switch inputs for immediate wireless transmission. Its ultra-low idle current and wide operating voltage make it ideal for embedded, battery-powered systems in industrial automation, smart home control, and wireless sensor networks where responsive, sub-0.2ms switching is critical.

Frequently Asked Questions

How do I pair and set up the ID learning function on this 2.4G RF transmitter module?

The module features built-in ID learning. Typically, you enter a specific learning mode by holding a configuration pin or sending a serial command sequence. Once in learning mode, press the button on your intended receiver or send its ID code. The module stores this paired ID in its non-volatile memory, enabling secure, interference-resistant communication. Refer to the specific protocol datasheet for the exact pin or command sequence to trigger the pairing process.

What is the recommended power supply configuration and wiring for reliable operation?

Supply a stable DC voltage between 1.8V and 3.6V to the module's VCC and GND pins. Ensure your power source can deliver brief current spikes during transmission. For optimal noise immunity, place a 10-100µF electrolytic capacitor and a 0.1µF ceramic capacitor close to the module's power pins. Connect your control signal (serial TX data or a physical switch) to the designated input pin. The module's low 24µA idle current makes it suitable for direct battery power from two AA cells or a small Li-ion cell.

Can I use this module to send custom serial data commands to a compatible receiver?

Yes, the module supports serial transmission. You interface by connecting your microcontroller's TX line (or a logic-level serial source) to the module's data input pin. The module will wirelessly transmit the serial byte stream you send. Ensure the baud rate matches the receiver's expectation (common rates are 9600 or 115200 bps). The built-in protocol handles packetization, error checking, and frequency hopping, providing a transparent wireless serial link for sending custom control commands or data packets.
