Emulate commercial remote controls and add wireless line-of-sight data transmission to your projects with this 38kHz IR Transmitter Module!
This compact infrared (IR) transmitter breakout board is engineered to broadcast modulated light signals at the industry-standard 38kHz carrier frequency. Unlike bare IR LEDs that draw too much current from microcontroller pins, this module features an onboard SMD transistor interface. This enables safe, high-speed switching directly driven by standard logic gates without risking component degradation.
Featuring an ultra-simple 3-pin interface (DAT, VCC, GND) and matching current-limiting resistors, it acts as the perfect hardware transmitter to control TVs, air conditioners, media centers, or custom infrared data links.
🚀 Key Features:
- Transistor-Driven Switching: Built-in signal amplification stage protects your microcontroller pins while ensuring maximum IR signal range.
- Standard 38kHz Compatibility: Fully compatible with common infrared remote protocols like NEC, RC5, and Sony codes.
-
Streamlined 3-Pin Layout: Labeled right-angle pins (
DAT,VCC,GND) offer easy, flat integration onto breakout shields and breadboards. - Onboard Power Indicator: Includes safety components and resistor arrays pre-soldered for immediate deployment.
🔧 Technical Specifications:
- Module Type: Infrared (IR) Transmitter
- Operating Frequency: 38kHz Modulation Compatible
- Operating Voltage: DC 3.3V – 5V
- Pin Configuration: Data Signal (DAT), Power (VCC), Ground (GND)
- Form Factor: Compact design featuring integrated corner mounting points.
💡 Common Applications:
- Building custom universal remote control devices using Arduino, ESP32, or Raspberry Pi.
- Setting up automated smart home bridges (e.g., turning on an AC unit or TV via a Wi-Fi command).
- Creating unidirectional, line-of-sight hardware communication triggers for robotics labs.
