ESP8266 Datasheet – ESP8266EX WiFi Module – Espressif

Part Number: ESP8266, ESP8266EX

Package : QFN32 Type

Manufacturer: Espressif Systems IOT Team


Espressif Systems’ Smart Connectivity Platform (ESCP) is a set of high performance, high integration
wireless SOCs, designed for space and power constrained mobile platform designers. It provides
unsurpassed ability to embed WiFi capabilities within other systems, or to function as a standalone
application, with the lowest cost, and minimal space requirement.

ESP8266EX Pinout


The ESP8266 WiFi Module is a self contained SOC with integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network. The ESP8266 is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor. Each ESP8266 module comes pre-programmed with an AT command set firmware, meaning, you can simply hook this up to your Arduino device and get about as much WiFi-ability as a WiFi Shield offers (and that’s just out of the box)! The ESP8266 module is an extremely cost effective board with a huge, and ever growing, community.

This module has a powerful enough on-board processing and storage capability that allows 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, including the 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.
