433 MHz 4‑Channel Wireless Remote Control Module – RF Transmitter & Receiver Pair

The 433 MHz 4‑Channel Wireless Remote Control is a complete RF transmitter and receiver module set designed for wireless control of electronic devices over a medium-range distance. It features 4 independent channels, allowing control of up to 4 different loads, making it ideal for DIY automation, security systems, garage door openers, and remote switching applications. The transmitter comes with 4 physical buttons corresponding to each channel, paired with a compact receiver module that features onboard relays or output pins to trigger external circuits. Operating at 433 MHz, it ensures stable signal transmission through walls and obstacles, with minimal interference. It supports momentary, toggle, or latching modes, depending on configuration (if supported by the receiver), and can be easily integrated into microcontroller-based or standalone control systems.

Key Features:

• 433 MHz RF remote control system with 4 independent channels
• Long-range wireless operation (typically up to 100 m open area)
• Transmitter powered by standard 12 V A23 battery (not always included)
• Receiver supports relay or logic-level output for direct control
• Wide compatibility with Arduino, Raspberry Pi, relays, and home automation setups
• Compact and lightweight design for easy integration and portability
