4-Key Wireless RF Module 433MHz Remote Control

The 4-Key 433MHz Wireless RF Remote Control Module is a versatile transmitter–receiver pair built for reliable short-to-medium range wireless control. The remote uses the popular SC2262 encoder chip while the receiver is based on the matching SC2272-M4 decoder, providing a stable, low-latency link suitable for switching loads, triggering events, or sending control signals to microcontrollers.

With four independent buttons mapped to four output channels (D0–D3), this module is ideal for projects that require multiple commands from a single remote — such as turning devices on/off, controlling motors in different directions, or activating alarm scenes. The receiver operates from a DC 5V supply, making it directly compatible with Arduino, Raspberry Pi, ESP32, and other common development boards.

The transmitter delivers a strong signal with a working distance of up to 120–150 meters in open areas, while the ASK modulation and rolling-code-style operation provide reliable performance even in environments with mild RF noise. The compact size of both the remote and the receiver module makes them easy to embed in enclosures, panels, or DIY product builds.
