Description

The 433MHz RF Transmitter and Receiver Module Link Kit is a low-cost wireless communication solution designed for Arduino, ESP32, Raspberry Pi, and other microcontroller projects. The kit includes one 433MHz transmitter module and one matching receiver module, allowing you to send data wirelessly between two devices over distances of up to 20–100 meters, depending on the supply voltage and antenna used. The modules operate on the license-free 433.92MHz ISM band using ASK/OOK modulation. The transmitter module operates from 3.5V to 12V DC, making it suitable for both 3.3V and 5V systems, while the receiver requires a stable 5V supply. The modules are commonly used in wireless remote controls,
