ESP8266 Serial Breakout

This little purple gem is a board that was gifted to me by a friend to do a review on and test out with my own setup. He designed it to be a drop in “shield” for Arduino mini or other breadboard mountable devices that follow the same pinout. It can also be used as a wifi to serial bridge and connect straight to a UART->USB header like the ones here. This is extremely useful when you have a complex piece of hardware that you want to control via WIFI but your dev board doesn’t have WIFI onboard. Watch the video after the break to see it in action bridging a Teensy 2.0 to an MQTT server to turn on and off an LED use this code.

The schematic eagle files can be found here if you want to take a look for yourself. If you just want to get one of the boards for yourself, the it can be found on OSHPark here.
