ESP-01 ESP8266 Serial WIFI Transceiver Module

The ESP-01 ESP8266 Serial WIFI
Wireless Transceiver 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 onboard 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-existing 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. In
the Documents section below you will find many resources to aid you in
using the ESP8266, even instructions on how to transforming this module
into an IoT (Internet of Things) solution!

Note:
The ESP8266 Module is not capable of 5-3V logic shifting and will
require an external Logic Level Converter. Please do not power it
directly from your 5V dev board.
