<div>= ESP8266 =<br />
<br />
The ESP8266 is a small, low-cost wifi-talking board. It's the new center of the Internet of Things. Originally intended as a "wifi modem", it exposes the WiFi interface over AT-style commands.<br />
<br />
Some hackers immediately noticed there is a general-purpose microcontroller on the box, and made a firmware for it that takes Lua programs. Now you don't need another microcontroller. Sweet!<br />
<br />
== Hardware ==<br />
<br />
For full specs, see [https://nurdspace.nl/ESP8266]. Important facts:<br />
* 3.3v *only* - 5v will let out the majikul smoke<br />
* Some reports say 1A current draw, others say 250 mA<br />
* Talks 802.1n, supports most major auth types.<br />
<br />
There are a number of ESP8266 hardware versions. The ones of interest are:<br />
<br />
* ESP1: 8 pins (basically one I/O plus power, etc.). Breadboard friendly (2.54mm), but not useful standalone<br />
* ESP12: 16 pins (I/O, power, 9 GPIO). Non-breadboard friendly: 2mm pin spacing<br />
<br />
== Software ==<br />
Folks seem to use [http://nodemcu.com/index_en.html NodeMCU], a Lua based firmware, when using the ESP alone.<br />

Prices are from the same store, and are competitive within a few cents.<br />
<br />
* ESP-12, Without breakout (Option A): $2.60 [http://www.aliexpress.com/store/product/Free-Shipping-10pcs-lot-ESP8266-remote-serial-Port-WIFI-wireless-module-through-walls-Wang-ESP-12/413752_32243298445.html aliex]<br />
