Preparing the Processor

The Huzzah ESP8266 breakout is the heart of the unit (https://www.adafruit.com/product/2471).  But before you can communicate with it you need to solder on a header to allow downloading the software.

Solder a 1×6 right angle male header onto the bottom part of the board.  Don’t attach any other headers at this time.

Although you can go ahead and assemble the unit, I prefer to load the software onto the board first.  I have had a couple of bad boards, so it is better to find out early instead of after you’ve soldered everything together.  Attach the console cable or FTDI cable.  You can see a tutorial on how to communicate with the board here.  A picture of how it is connected using a USB console cable is show

We’ll load the firmware onto the board in the next step
