4-Channel Infrared Remote Control Module Kit with 5-Key IR Remote and Transmitter

The 4ch infrared module is a complete infrared remote control kit that pairs a four-channel receiver board with a five-key infrared remote control and an IR transmitter module. It is designed for users who want to add remote switching to an Arduino project, a robotic platform, or a smart-home device without building an infrared receiver from scratch. The receiver board decodes the incoming infrared signal with an onboard microcontroller and exposes four independent output channels, each of which can be read as a high or low logic level by a host controller.

The IR remote control switch 4 channel operates in a jog-type mode. When the CH1 key on the remote is pressed and held, the OUT1 port on the receiver board outputs a high level and the corresponding indicator LED lights; when the key is released, the output returns to a low level and the LED turns off. The same behavior applies to CH2 through CH4, which map to OUT2 through OUT4. The power key on the remote controls all output ports simultaneously, allowing the entire group to be switched on or off from a single button. The board is powered from a 3V to 5V DC supply, draws less than 1mA in static operation, and measures only 10mm × 15mm, making it easy to embed in small enclosures.

The receiver board’s compact size and low current consumption make it suitable for battery-powered and space-constrained projects. Because the outputs are simple high/low IO signals rather than relay contacts, the module is best suited to driving logic-level inputs, small LEDs, or external relay boards rather than switching mains loads directly. Typical applications include appliance control, robotics, garden equipment, and smart-device prototyping. The kit includes the receiver board, the five-key remote, and an infrared transmitter module, providing the essential hardware for a complete remote-control link.
