4Ch – 27 MHz RC Control Board

A 4CH – 27 MHz RC control board is typically used in remote-controlled (RC) toys like cars, boats, or robots. Here's a quick overview of what it is and how it works:

Key Features:

• 4 Channels (CH): This means the board can control 4 separate functions. Common ones are:

  1. Forward

  2. Backward

  3. Left

  4. Right

• 27 MHz Frequency: Refers to the radio frequency used for wireless communication between the transmitter (remote) and receiver (control board). It’s a standard RC frequency.

• Simple Operation: Often uses H-bridge circuits for motor control and relays or transistors to switch directions.

• Applications:

  • Toy RC cars

  • DIY RC boats

  • Basic RC robotic platforms
