ESP-12E is a miniature Wi-Fi module present in the market and is utilised for establishing a wireless network connection for microcontroller or processor. The core of ESP-12E is ESP8266EX, which is a high integration wireless SoC (System on Chip). It functions ability to embed Wi-Fi capabilities to systems or to function as a standalone application. It is a low cost solution for developing IoT applications.
Overview of ESP-12E
ESP-12E is a member of ??ESP-XX?¡¥ series. Although all of them are based on ESP8266 SoC they differ in on output pins, flash memory and antenna type. These modules numbered from ESP-01 to ESP-15 and are best in performance and cost. Many engineers use these modules to setup a wireless communication between two applications. For data sharing and IoT you will find these modules Ideal.
How to use the ESP-12E
This module does not have complex circuitry or programming so using this module is very easy. We will construct a simple application circuit for understanding the module working.
Steps for setting up a simple application circuit:
Connect positive +3.3V power to the module.
Interface module to a microcontroller or ARDUINO using UART (Connect RXD of ESP to RXD of |¨¬C & TXD of ESP to TXD of |¨¬C).
Download the libraries to the module from the internet. For ARDUINO, the IDE will have pre-installed libraries. If you do not have them just update the libraries from ARDUINO website.
Write the program for setting up the baud rate and data exchange.
Send data to the module for transmitting through Wi-Fi or Receive data from the module that was transmitted via Wi-Fi.
There is another way for setting up the module which is to bypass microcontroller and directly connect the module to PC using FTDI. After interface you can use serial monitor to communicate using the module.
