433MHz 4-Channel Wireless RF Remote Control & Receiver Module Kit

Simple Wireless Control

This RF kit operates on the widely used 433MHz frequency, providing a reliable wireless link that can pass through walls and obstacles. The receiver module features four output pins that correspond to the four buttons on the remote. When a button is pressed, the corresponding pin on the receiver goes HIGH, allowing you to trigger microcontrollers like Arduino or drive relay modules directly.

Versatile DIY Applications

Designed for simplicity, this kit uses “Non-Locking” (Momentary) mode by default—the output stays HIGH only as long as you hold the button. This makes it perfect for momentary actions like opening a gate, ringing a wireless doorbell, or momentary motor control. With four separate channels, you can manage multiple devices using a single, compact remote.

Key Features

• 4-Channel Independent Control: Trigger four different outputs from one remote.

• Plug-and-Play Setup: No complex coding required; works right out of the box.

• Compact Keychain Remote: Portable, durable, and features a sliding cover to prevent accidental button presses.

• High Sensitivity: Reliable signal reception even at a distance (up to 50-100m in open areas).

• Arduino Compatible: The receiver pins output 5V logic, making it easy to interface with any microcontroller.
