Description

4 Channel Wireless RF Remote Control with Receiver (315MHz, Non-Locking)

The 4 Channel Wireless Four Button RF Remote Control Transmitter & Receiver Module is a reliable and easy-to-use solution for wireless control applications. It consists of a fixed-code RF transmitter and a 4-channel receiver board, allowing users to build custom wireless remote-control circuits with minimal effort.

Widely used by electronics hobbyists, students, colleges, and industrial designers, this module works as an excellent single-chip signal input source for microcontroller-based projects, remote switching, and automation systems.

How It Works

  • When a button is pressed, the transmitter powers up and sends data packets at 315MHz, containing its unique ID and button data.
  • Each transmitter has a factory-programmed unique ID that cannot be changed.
  • The receiver responds only to stored transmitter IDs, enabling secure operation.
  • The RF section uses a SAW-based 315MHz ASK transmitter, compatible with standard ASK RF receivers and decoder circuits.

Button & Output Mapping

  • Button 1 → Output D0
  • Button 2 → Output D1
  • Button 3 → Output D2
  • Button 4 → Output D3
  • When a button is pressed, the corresponding output goes HIGH

Operating Modes

  • Non-Locking Mode (Default): Output remains HIGH only while the button is pressed and returns LOW when released. Ideal for door locks, relays, and MCU triggers.
  • Self-Locking Mode (Optional): Each press toggles the output ON/OFF. Useful for lights or motors.
  • Interlocking Mode (Optional): Only one output can be active at a time; activating one disables others. Suitable for fan speed selectors or multi-state control.

Caution

  • Do not touch or bend the onboard copper coil (inductor) on the receiver.
  • Physical movement of the coil can alter inductance and cause improper operation.

Receiver Pin Configuration

  • VT – Valid transmission indicator (HIGH on signal reception)
  • D3 – Data output (Button 4)
  • D2 – Data output (Button 3)
  • D1 – Data output (Button 2)
  • D0 – Data output (Button 1)
  • +5V – Power supply positive
  • GND – Power supply ground
  • ANT – Antenna terminal

Antenna Recommendation

For best transmission distance, use a quarter-wavelength antenna:
  • Type: 50-ohm single-core wire
  • Recommended Length: 17 cm
