The Wireless RF Encoder & Decoder Board with 433 MHz Module is a reliable and easy-to-use wireless communication solution designed for remote control, automation, and embedded electronics projects. Operating on the popular 433 MHz RF frequency, this module pair enables stable short-range wireless data transmission without the need for complex networking or protocol stacks.

The system consists of an encoder board (HT12E compatible) for transmitting digital signals and a decoder board (HT12D compatible) for receiving and decoding the data. Using ASK / OOK modulation, it ensures efficient and low-power communication suitable for remote switching and control applications.

Powered by a 5V DC supply, the boards provide digital output signals that can be easily interfaced with popular microcontroller platforms such as Raspberry Pi, ARM, DSP, AVR, PIC, and 8051. In open areas, the communication range can reach up to 100 meters, making it ideal for wireless control applications.

This RF encoder and decoder set is widely used in wireless switch systems, robot remote control, home automation, wireless doorbells, alarm systems, and DIY RF communication projects. Its plug-and-play design allows beginners to quickly implement wireless control, while still offering reliability for advanced embedded applications.
