A microcontroller board based on the atmega328 is called the Arduino Uno (data sheet).
It features a 16 MHz crystal oscillator.
6 analogue inputs.
14 digital input/output pins (six of which can be used as PWM outputs).
A USB-port.
A power Jack.
An ICSP header.
And a reset button.
It comes with everything needed to support the micro controller.
All you need to do is use a USB cable to connect it to a computer or an AC-to-DC adapter or battery to power it.
The FTDI USB-to-serial driver chip is not used by the Uno.
Setting it apart from all previous boards.
It has the Atmega8U2 configured to function as a serial-to-USB converter.
