ESP8266 Wifi Module - (AD52998)

Description:

This is the greatest Internet of Things board. Easy to connect and powerful enough to pull data from sensor without the use of a dedicated microcontroller. A wealth of information and a great community have made this one of the best choices for making your toaster tweet to the world, updating your pianos Facebook page, automating your juicer, turning off or on your lights, the options are endless!

This little WIFI connected board is now Arduino supported. To use the Arduino IDE with this board you need Arduino IDE version 1.6.4 or greater. Follow the instructions here for a quick rundown on how to install the ESP8266 module for the Arduino IDE HERE.

This is an ESP-07 version of this board. There is an onboard antenna on this board with a U.FL connector for an optional antenna.

Wiring the ESP8266 is relatively straightforward. To program this board you will need a USB to Serial converter and the CP2102 is up to the task. This board has a 3.3V line.

An example of wiring with our CP2102 is shown. The GPIO0 pin needs to be pulled to ground when powered on for the CP2102 to enter upload mode.

If you follow this wiring guide, including the LED, and have everything set up and running you should be able to upload this script. It is a slightly modified Blink script for the ESP2866 so you can blink the LED and see an output to the serial port.

The biggest difference is that the LED_BUILTIN is on a different pin for the ESP-07 module. So you need to define that to a different GPIO pin, in this case, pin 5.

Now that you can flash Arduino Sketches to the ESP2866 be free! Be free and connect the world to the internet! Not the Internet of Things... it's the Internet of Everything! with the ESP2866.
