433MHz Wireless Remote Control Transmitter (4-Button)

This transmitter is designed for compatibility with learning code receiver modules that use the EV1527 or similar PT2262/2272 chipset protocols. You will need a compatible 433MHz receiver that supports the same fixed, learning, or copy code working mode for successful pairing and operation in your system.

For learning code receivers, typically you press a 'learn' button on the receiver, then press a button on the remote to transmit its unique code. The receiver stores this code. For fixed code systems, ensure the transmitter and receiver share the same address and data code settings, often set by DIP switches or soldering pads on the PCB.

The remote is battery-powered, but the specific battery type and voltage are not included. Most 433MHz remotes of this size use a 12V battery (like A23 or 27A) or a 3V coin cell (CR2032). Check the battery compartment markings. The low 11mA operating current ensures good battery life for typical intermittent use.

Yes, if your receiver supports learning multiple transmitter codes. For learning code systems, you can typically teach the receiver to recognize codes from several different remotes. For fixed code systems, all remotes must be configured with identical address and data codes, which limits flexibility.
