Wireless RF Remote Control 4 Keys 433 Mhz (4CH , 4 Channel)

The 433MHz 4-Channel Wireless RF Remote Control Kit is a versatile wireless control system designed for remote switching and automation applications. The kit includes a compact 4-channel RF receiver board and a 4-button wireless transmitter operating on the 433MHz frequency band.

The receiver module operates from a 5V DC power supply and provides four independent output channels (OUT1–OUT4). Each channel can be controlled wirelessly using the included RF remote transmitter. The module supports multiple configurable operating modes including momentary (jog), self-locking, and interlocking modes, allowing flexible use in different automation and control systems.

The learning-type receiver supports custom pairing with remote buttons through a simple onboard learning process. Users can easily program, switch modes, or clear saved remote settings using the built-in learning button and LED indicator.

With communication distances ranging from 15 to 30 meters depending on environmental conditions, the module is suitable for wireless switching, smart home projects, remote lighting control, security systems, motor control, and embedded electronics applications.
