no link, the place i bought mine from in august doesn&#x27;t appear to have any anymore.<p>i recommend buying the esp-12e, and the first one on my search comes up at $1.97.  note, these things aren&#x27;t breadboard friendly out of the box.  if you want that, buy a huzzah from adafruit or buy one of the breakout boards on aliexpress (17 cents each or so).
