433MHz RF Transmitter & Receiver Module (HT12E/HT12D Encoder–Decoder Kit)

This 433MHz RF wireless communication module is a reliable transmitter and receiver set designed for short-range wireless control projects. Built around the widely used HT12E encoder and HT12D decoder ICs, it converts parallel data into a serial RF signal for transmission and accurately reconstructs it at the receiver end for seamless device control.

Ideal for Arduino, microcontroller, and embedded systems projects, this module allows easy wireless switching, automation, and remote control applications.

Key Features:

• Operates on stable 433MHz RF frequency

• Based on HT12E (4-bit encoder) and HT12D (4-bit decoder)

• Converts 12-bit data (8 address + 4 data bits) into serial RF transmission

• Reliable address validation ensures correct data reception

• 4-bit digital output (D0–D3) on receiver side

• Jumper-selectable address pins for flexible configuration

• Compatible with microcontrollers and digital control systems

• Easy connection via male header pins

• Supports push buttons or digital inputs (4.5V – 5V logic interface)

Electrical Specifications:

• Operating Voltage: 7V – 12V

• Frequency: 433MHz

• Transmission Range: ~10 meters (typical, environment dependent)
