Infrared IR Wireless Remote Control Module Kit HX1838 for Arduino

The HX1838 Infrared (IR) Wireless Remote Control Module Kit is a compact, reliable solution for adding IR control to your Arduino, Raspberry Pi, and other microcontroller-based projects. It includes an ultra-slim 20-key remote and a 38 kHz IR receiver module, enabling quick prototyping of robots, automation systems, and interactive electronics.

✨ Key Features

• 🎯 38 kHz IR receiver for standard remote control signals
• 🧭 20-function ultra-thin remote for intuitive input
• 📡 Transmission range: up to 8 meters (line-of-sight, indoor)
• 🔌 Simple 3-pin interface: VCC, GND, OUT
• 🛠️ Easy integration with Arduino libraries (e.g., IR decoding)
• 🤝 Works with Raspberry Pi, ESP32/ESP8266, and other electronics modules

📐 Specifications

• Receiver type: HX1838-based 38 kHz IR demodulating receiver
• Remote control: 20 keys, ultra-slim form factor
• Carrier frequency: 38 kHz
• Typical range: up to 8 m (indoor, direct line-of-sight)
• Interface: 3-pin module (VCC, GND, OUT), digital TTL output
• Use case: Indoor equipment control and prototyping

Note: The receiver module is commonly powered from a 5 V microcontroller supply. Signal output is suitable for reading on typical GPIO pins. Always verify voltage levels and GPIO tolerances on your target board.

🔌 Pinout

• VCC: Power input (typically 5 V from the microcontroller board)
• GND: Ground
• OUT: Demodulated digital IR signal to a GPIO pin

⚙️ Compatibility

• Arduino UNO, Mega, Nano, Leonardo, and compatible boards
• Raspberry Pi (via GPIO with suitable wiring)
• ESP32 / ESP8266 and other microcontroller platforms

🚀 Typical Applications

• Remote-controlled robotics and mobile platforms
• Home automation and smart electronics control
