Arduino Diecimila

Overview
The Arduino Diecimila is a microcontroller board based on the ATmega168. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, 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 a AC-to-DC adapter or battery to get started.

"Diecimila" means 10,000 in Italian and was named thusly to mark the fact that over 10,000 Arduino boards have been made.
