Wiring up the ESP8266

Before you can program the ESP8266, you need to wire it up.

First things first, the ESP8266 uses a 2mm pin spacing so you can’t use a standard breadboard as these use a 0.1 inch spacing. It also uses 3.3V logic, so you need to use a 3.3V serial adaptor or a 5V one with a level shifter.

Ideally, you will need the following things:

  • USB to 3.3V TTL serial adaptor (I use an FTDI TTL-232R-3V3)
  • ESP8266
  • 3.3v DC supply (capable of providing ~400mA)
  • Small SPST switch – Optional to switch between Run/Program mode
  • Momentary push button – Optional reset button
  • 4 x ~10k resistors
  • ~100nF capacitor

I wired up my ESP8266 like this (Source: https://github.com/esp8266/Arduino/blob/master/doc/boards.md#improved-stability)

Introducing the ESP8266

About a year ago I put up some money for the Wino-Board kickstarter project, received my Wino-Boards and did nothing with them for 12 months. They are effectively a tiny Arduino board attached to the innards of an ESP8266 WiFi module.

I finally had a play with them last week and after making a few changes to the Wino-Board libraries (The current version could not do an HTTP GET), I found them very easy to use.

The more intriguing thing about the Wino-Board was finding out more about the ESP8266 module and that it is now possible to directly program the module itself using the Arduino IDE.
