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.

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!


For full specs, see [1]. Important facts:

  • 3.3v *only* - 5v will let out the majikul smoke
  • Some reports say 1A current draw, others say 250 mA
  • Talks 802.1n, supports most major auth types.

There are a number of ESP8266 hardware versions. The ones of interest are:

  • ESP1: 8 pins (basically one I/O plus power, etc.). Breadboard friendly (2.54mm), but not useful standalone
  • ESP12: 16 pins (I/O, power, 9 GPIO). Non-breadboard friendly: 2mm pin spacing


Folks seem to use NodeMCU, a Lua based firmware, when using the ESP alone.
