Arduino UNO R3 USB Microcontroller Development Board

Arduino Uno compatible microcontroller board based on the ATmega328. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega16U programmed as a USB-to-serial converter.

This new enhanced version includes additional holes to fit male header strips (included) next to the standard female headers plus additional serial port and I2C bus access points.

Features

• digital I/O pins: 14 (of which 6 provide PWM output)
• analogue input pins: 6
• Board components include: 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button
• USB lead supplied (colour may vary from image)

Specifications

• power supply: 6-20 V max. (adaptor not included)
• microcontroller: ATmega328
• digital I/O pins: 14 (of which 6 provide PWM output)
• DC current per I/O pin: 40 mA
