This Arduino Uno Pinout is a 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 adaptor or battery to get started. The Arduino Uno Pinout 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.
