Overview
The Arduino Uno Wi-Fi is the new Arduino Uno with an integrated Wi-Fi module!The board
is based on the ATmega328P (datasheet (http://www.atmel.com/images/Atmel-8271-8-
bit-AVR-Microcontroller-ATmega48A-48PA-88A-88PA-168A-168PA-328-
328P_datasheet_Complete.pdf)) with an ESP8266 Wi-Fi Module integrated (datasheet
(http://download.arduino.org/products/UNOWIFI/0A-ESP8266-Datasheet-EN-v4.3.pdf)).It
has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a
16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset
button. It contains everything needed to support the microcontroller; simply connect it to a
computer with a USB cable or power it with an AC-to-DC adapter or battery to get started.
The ESP8266 Wi-Fi Module is a self contained SoC with integrated TCP/IP protocol stack
that can give access to your Wi-Fi network. (Or the device can act as an access point.) One
useful feature of Uno Wi-Fi is support for OTA (over-the-air) programming, either for
transfer of Arduino sketches or Wi-Fi firmware.
