{"title":"Adafruit Infrared IR Remote Transceiver - STEMMA JST PH 2mm","handle":"adafruit-infrared-ir-remote-transceiver-stemma-jst-ph-2mm-ada5990","url":"/products/adafruit-infrared-ir-remote-transceiver-stemma-jst-ph-2mm-ada5990","description":"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.\n\nConnect 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.\n\nKey Features\n\n\nCombined Transmitter & Receiver – Send and receive 940 nm, 38 kHz IR remote signals from one board\n\nHigh-Power IR Transmitter – Two IR LEDs with FET driver; 200 mA per LED at 5V (400 mA total pulsing)\n\n10+ Metre Range – Dual LED orientation (vertical + horizontal) for wide coverage\n\n38 kHz IR Receiver – Demodulated signal output ready for microcontroller decoding\n\nSTEMMA JST PH 2 mm Connector – Solderless 4-pin connection (power, ground, data in, data out)\n\n3V – 5V Compatible – ~200 mA total at 3V or ~400 mA total at 5V when transmitting\n\nStatus LEDs – Yellow \"IN\" LED for transmit activity and yellow \"OUT\" LED for received signals\n\nBreadboard Option – 0.1\" header pads available for soldered connections\n\n\nIdeal For\n\nIR remote control transmitter and receiver projects\nHome automation IR blasters with receive feedback\nUniversal remote control systems\nProjects needing both IR send and receive without two separate boards\n\n\nPackage Contents\n\n1× Adafruit Infrared IR Remote Transceiver Board (assembled and tested)\n\n\n\nImportant: This board does not use I2C. The 4-pin JST PH cable carries: red = 3–5V power, black = ground, white = data to IR LEDs, green = demodulated IR signal from receiver.\n\n\n\nNote: STEMMA JST PH cable not included. This board is for 940 nm, 38 kHz IR remote control signals only — not suitable for proximity sensing or other frequencies. Your microcontroller must support pulse-input reading and IR decoding.\n\n\nResources\n\nAdafruit IR Transceiver Guide\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":978,"title":"Default Title","sku":"AF-5990","mpn":"ADA5990","price":11.52,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":3,"option1":"Default Title"}]}
