Required Materials

The ESP8266 Shield surrounds the WiFi SoC with everything it should

need to operate and connect to a WiFi network. All you need to add to it are

headers, some solder, and an Arduino. Here are a list of parts we use in the

tutorial, in case you want to follow along:

Instead of the RedBoard, you should be able to use almost any other

Arduino-compatible development board – the Uno or Leonardo for example.

You’ll also need a set of soldering tools, if you don’t already have them. A

simple iron and some solder should really be all you need.
