4 Channel RC Remote Control...

A 4-Channel RC Remote Control System (27MHz) with Transmitter & Receiver PCB is a radio frequency (RF) control system commonly used for remote-controlled (RC) cars, boats, robots, and DIY electronics projects.

Specifications

Transmitter (Remote Control PCB)

  • Frequency: 27MHz
  • Channels: 4 independent channels (for forward, backward, left, right, or custom actions)
  • Operating Voltage: 9V (usually powered by a 9V battery)
  • Transmission Range: ~30–100 meters (depends on antenna and environment)
  • Modulation Type: AM (Amplitude Modulation) or FM (Frequency Modulation) (varies by model)
  • Antenna: External telescopic or wire antenna for better range
  • Control Type: Push buttons or joystick-based

Receiver Board (PCB Module)

  • Operating Voltage: 5V – 12V DC (depends on the module)
  • Outputs: 4-channel relay or motor driver outputs
  • Antenna: Wire or coil antenna for better signal reception
  • Interface: Solder pads or screw terminals for motor or relay connections
  • Decoding Method: Can use HT12D (for AM systems) or custom ICs
  • Control Signal Type: Digital HIGH/LOW outputs for each channel

Key Features

Simple RC Communication – Ideal for beginners and DIY hobbyists
Multiple Channels – Control 4 different functions (e.g., motors, servos, relays)
Long-Range Operation – Works within 30-100 meters
Compatible with RC Cars, Boats & Robots
DIY-Friendly – Can be used for custom-built RC systems

Common Applications

  • RC Cars, Trucks, and Boats – Standard 4-channel control setup
  • DIY Robotics – Remote control for robotic arms, drones, or automation systems
  • Wireless Switching Systems – Control LEDs, motors, or appliances remotely
  • Educational Projects – Great for electronics learning and prototyping

Additional Considerations 

  • If you need a higher range, consider upgrading to 2.4GHz RC modules for better interference resistance.
  • If you need bidirectional communication, look for systems with RF transceivers (both transmit & receive capabilities).
