The Adafruit Infrared IR Remote Transceiver combines a high-powered IR transmitter and a sensitive 38 kHz IR receiver on a single board. With two 940 nm IR LEDs (one vertical, one horizontal) driven by an onboard N-channel FET at 100–200 mA per LED, you get 10+ metres of transmit range alongside a demodulated receiver output — all in a solderless STEMMA JST PH package.

Connect with a single 4-pin JST PH cable: power, ground, data in (to IR LEDs), and data out (from IR receiver). Yellow status LEDs labelled "IN" and "OUT" blink to indicate transmit and receive activity respectively.

Key Features

• Combined Transmitter & Receiver – Send and receive 940 nm, 38 kHz IR remote signals from one board
• High-Power IR Transmitter – Two IR LEDs with FET driver; 200 mA per LED at 5V (400 mA total pulsing)
• 10+ Metre Range – Dual LED orientation (vertical + horizontal) for wide coverage
• 38 kHz IR Receiver – Demodulated signal output ready for microcontroller decoding
• STEMMA JST PH 2 mm Connector – Solderless 4-pin connection (power, ground, data in, data out)
• 3V – 5V Compatible – ~200 mA total at 3V or ~400 mA total at 5V when transmitting
• Status LEDs – Yellow "IN" LED for transmit activity and yellow "OUT" LED for received signals
• Breadboard Option – 0.1" header pads available for soldered connections

Ideal For

• IR remote control transmitter and receiver projects
• Home automation IR blasters with receive feedback
• Universal remote control systems
• Projects needing both IR send and receive without two separate boards
