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).
