This board is an ATMEGA328 Microcontroller development board. The ATMEGA328P-PU is a high performance, low power AVR 8-Bit Microcontroller. The baord has 14 digital input/output pins (6 of which can be used as PWM outputs) and 6 analog pins.

This board inherits all of Arduino Duemilanove's and Uno's features but also adds some of its own. This board is compatible to Duemilanove's and Uno's pin layout, and the Duemilanove's screw holes and board dimensions.

Detailed specifications:

• ATmega328 microcontroller with Optiboot (UNO) Bootloader
