ESP8266 WiFi UART Serial Module ESP-12

With breakout board and battery holder.

This module uses 3x AA batteries (not included) and has a 3.3V regulator onboard. Additionally:  

1x Power indicating blue LED
6x Red LEDs mapped to GPIO pins
1x RGB 5mm LED mapped to GPIO pins
1x CdS photo-resistor mapped to ADC GPIO pin

Additionally, pins on the ESP are broken out to pin headers. 

Android Demo App: https://play.google.com/store/apps/details?id=com.duvallsoftware.iotdemoapp

  1. Download the app, power the module and connect to the AI-THINKERxxxxx WiFi Network using password: ai-thinker
  2. Open the app and connect to the device, you can now control the LEDs and read the ADC value
  3. Optional step: Connect the ESP8266 module to your home/work WiFi network using the app. Setup the external IP address to match that given by the router the the ESP. You can now control the device from your network!

Overview

The ESP8266 is a highly integrated chip designed for the needs of a new connected world and is the go to choice for IOT. It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor.

ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area. The ESP8266 supports APSD for VoIP applications and Bluetooth co-existance interfaces, it contains a self-calibrated RF allowing it to work under all operating conditions, and requires no external RF parts.

There is an almost limitless fountain of information available for the ESP8266, all of which has been provided by amazing community support.
