## Description

This interesting module is a lot of fun for hobbyists and students who are interested in experimenting with the ESP8266 WiFi chipset. We bought a bunch of these modules, updated the firmware to the much-easier-to-use v0.924 and wrote some Arduino code to grab a webpage.

We do not have a detailed tutorial at this time, this chipset/module is for the curious and adventurous! There's tons of details and experiementation over at http://www.esp8266.com

This module is very low cost, but very simple. It doesn't support SSL, or communcation over SPI - just UART! It doesn't have 5V to 3V logic level shifting [so you'll probably want to pick up a logic level shifter](https://www.adafruit.com/product/757), it also doesn't have a regulator on board and it can use big spikes of 300mA or more current at 3.3V so if using with an Arduino, [an external 3V regulator is essential!](https://www.adafruit.com/product/2165) (Seriously don't try to power it from the 3.3V power pin the Arduino!) Also, the connector is kind of annoying and not breadboard-friendly, [some female-to-male wires can help out in that case](https://www.adafruit.com/product/1953) to make it easy to plug into a breadboard

That said, it does do the job, and [can be used as a UART-at-9600-baud to WIFI adapter using our example code for Arduino](https://github.com/adafruit/Adafruit_ESP8266) or, for the *really* adventurous, programmed directly using an SDK

\- Again, we do not have a detailed tutorial at this time! Right now, we're offering this for experimenters' use only - we cannot offer support, returns or refunds for this product.
