433MHz 12V 1-Channel RF Relay Module with Wireless Remote Control – EV1527
Product Description
The 433MHz 12V 1-Channel Wireless RF Relay Module is a compact remote-control switching solution for compatible electronic and automation projects. Operating on a 433MHz RF frequency, it allows you to switch one electrical load wirelessly without requiring Wi-Fi, Bluetooth, an internet connection, or a mobile application.
The receiver operates on a 12V DC power supply and is supplied with an L-U style wireless remote transmitter. It supports compatible fixed-code and learning-code remote controls, with EV1527 learning-code compatibility specified for suitable transmitters.
This module is useful for DIY electronics, wireless lighting control, low-voltage automation, robotics, and other projects that require convenient remote switching.
