WiFi IR Blaster - ESP8266

Added to your shopping cart

The WiFi IR Blaster is designed to connect all of your legacy IR-controlled devices to a WiFi network – exposing them to a new horizon of control. Want to control your TV via a web-browser? Want to ask Alexa to mute your stereo? Want to schedule triggers to your IR-controlled LED strip? These are all applications that the WiFi IR Blaster is perfect for.

The IR Blaster combines an ESP8266 – a powerful WiFi/microcontroller SoC – with an IR emitter and receiver. With built-in WiFi support, the ESP8266 can be programmed to provide an interface between HTTP, MQTT, TCP, and UDP services and the infrared-controlled devices populating your entertainment center.

This product includes the WiFi IR Blaster, a Lite-ON LTE-302 infrared emitter, and a TSOP38238 IR receiver. The IR emitter and detector are not populated on the board – allowing you to assemble them in any orientation your project requires.

This board works with the ESP8266 Arduino hardware definitions and is designed to be programmed with a 3.3V 6-pin USB-to-serial converter – we recommend either the Beefy 3 FTDI Basic Breakout or Serial Basic Breakout - CH340G (something with a 3.3V regulator that can supply enough power to the ESP8266 and IR emitter).

For help getting started, check out our WiFi IR Blaster Hookup Guide, which explains how to assemble the board, program it, and use the IRremoteESP8266 Arduino library.

Great little board for remote IR control

Needed a way to programmatically change channels on TV set top box for a DIY DVR. This board is really easy to program. Now I have a tiny http API server to change channels with no cables required.

Easy to get up and running, well-designed

I’ve struggled in the past with debugging IR transmitter circuits, and this will be my new go-to board for IR applications. The ESP is easy to work with as well, and getting from Hello World to my desired application (custom intervalometer for Sony NEX-5T) took less than an afternoon. Hooray! The only improvements/additions I’d want are: battery-management onboard, onboard on/off switch, and an easier way to mount this into an enclosure. But for this price, it’s a great deal.
