ESP8266 ESP-03 ESP03 WIFI Module

Ideal for Arduino / Pic WIFI Projects

Or use standalone without a separate micro

for ESP-Arduno, LUA, or ESP-Basic

Connects to existing router, Create an access point or even both at the same time!

Wifi Client, server mode or both together.

Supports WPA/WEP/Open Encryption types.

Ideal for Arduino / PIC / MSP430 / STM32 internet of things projects

This module does all the complicated TCP/IP or UDP stuff, you just configure the wifi settings,

request a webpage and process the results, or send logging data to a server.

All communication with the device is done using AT commands through it's serial port

e.g. AT+RST (resets device), AT+CIFSR (display IP addresses), AT+CWLAP (list all access points in range) - Simples!! :-) :-)
