Cheap Wifi – The ESP8266

As someone who loves making WiFi enabled projects one of the gotchas is the cost of the WiFi chip! I have used a few different ones, each with their advantages.

  • ElectricImp (~$40) – Closed source, own cloud
  • SparkCore (~$40) – Open source, own cloud.
  • RN-XV WiFly (~$50) – Proprietary, no cloud.

But something else has come on the scene! The ESP8266 is a WiFi module coming in at the low cost of $5! What the! I am sure that at industrial scale $5 or cheaper WiFi chips are standard but from my knowledge this is a bit of a first for the Maker scene. To me this will open up the Internet of Things (IoT) to get past the barrier of cost making devices more pervasive!
