Product Description
Take instant, wireless command over your environment with the 4-Channel RF Remote Control with Receiver Set. Precision-engineered by Muonix, this matched transmitter-and-receiver pair lets you add long-range wireless remote control capabilities to any electronics project, microcontroller system, or hardware prototyping array without complex coding.
Operating on the ultra-stable 433MHz Radio Frequency (RF) spectrum, this system works reliably through walls, glass, and doors without requiring a direct line-of-sight. This kit is an excellent choice for deploying remote gate controllers, wireless security alarms, automated lighting switches, and multi-channel robotics setups.
Key Features
Complete Plug-and-Play Wireless Solution: Ships as a fully matched pair featuring a 4-button handheld remote transmitter and a compact, high-sensitivity receiver board.
Long-Range Penetration: Utilizes high-performance RF decoding circuitry to transmit clear, stable wireless commands over distances of 50 to 100 meters in open environments.
4 Independent Digital Outputs: The receiver board features 4 distinct data output pins (D0, D1, D2, D3) corresponding exactly to the four buttons (A, B, C, D) on the remote transmitter.
Hardware Status Indicator: Equipped with an onboard VT (Valid Transmission) LED that lights up instantly whenever the receiver picks up a valid signal from the remote.
Ultra-Low Power Footprint: The receiver circuit operates from a standard 5V DC power supply and consumes minimal standby current, making it suitable for battery-backed security and automation applications.

Build Quality
Precision-manufactured receiver module with high-quality electronic components.
Factory-assembled and tested for reliable wireless communication.
Durable PCB construction designed for long-term performance in automation, control, and embedded system applications.
Pinout Mapping & Interfacing
The receiver board provides standard 0.1-inch header pins, making it breadboard-friendly and easy to interface directly with Arduino, Raspberry Pi, ESP32, STM32, and other development platforms.
VCC: +5V DC Power Input
GND: System Ground Reference
D0, D1, D2, D3: Digital output pins. When a button on the remote is pressed, the corresponding pin outputs a HIGH (5V) signal.
VT (Valid Transmission): Outputs a HIGH signal whenever any valid button press from the paired remote is received.
ANT: Unpopulated pad for soldering an optional 17cm wire antenna (433MHz) to maximize operating range.
