Things You Should Know Before Buying ESP8266 Wifi Module

Things you should know about using ESP8266 WiFi module for its safety and easiness as it’s a very delicate module to use.

ESP8266 is a 3V Wifi Module very popular for its Internet Of Things Applications. ESP 8266 maximum working Voltage is 3.6V and it’s very important to note. you must know how to power it, How to Serial Connect it with Arduino Safely, How To Ping, and many other things. You should Use Software Like Circuito.io, Tinkercad, and Fritzing to stimulate and work with the board Safely. You should also use the Logic Level Controller To use with the ESP8266 Module.


What Is ESP8266 Wifi Module?

The Espressif system created the ESP8266, a system on chip (SoC) module with Wi-Fi capabilities. It is mostly utilized for the creation of embedded Internet of Things (IoT) applications. The ESP8266 is a low-cost Wi-Fi microprocessor manufactured by Chinese manufacturer Espressif Systems in Shanghai. It has a full TCP/IP stack and microcontroller capabilities.

The ESP8266 is capable of offloading all Wi-Fi networking tasks from another application processor or hosting an application. Each ESP WIFI module is already pre-programmed with an AT command set firmware, so all you need to do is connect it to your Arduino project to receive the same level of Wi-Fi functionality as a Wi-Fi Shield. The ESP8266 module is a very affordable board with a sizable and rapidly expanding community.



2014 saw the introduction and development of the ESP8266 Wi-Fi module, which is mostly used for developing embedded IoT applications. Manufacturers like AI thinking introduced and developed the device. With the use of a distinct application processor, it may control multiple Wi-Fi network operations.


It is a System-On-Chip (SOC) with the TCP/IP protocol stack incorporated that can connect a microcontroller to any Wi-Fi network. The pin configuration, specifications, circuit diagram, applications, and alternatives of the ESP8266 Wi-Fi module are covered in this blog. Read the blog to know all the essential factors to consider when purchasing an ESP8266.
