Hardware Overview
The WiFi IR Blaster is based around the ESP-12S ESP8266 module. This module equips the ESP8266 with a
crystal, 4Mb flash, and PCB antenna – just about everything it needs to get going. The antenna sits under the
SparkFun logo, so try not to place anything that may interfere with WiFi signals near that area.
Supporting the ESP8266 are a reset and general purpose button, a user LED, and an array of pin breakouts.
Of course, there’s also the IR emitter and detector. These components are packaged with the board, but not
soldered in place. This allows you to solder both components at any angle your project requires. It also leaves the
option to customize the board and spec out your own emitter and/or receiver.
