OVERVIEW
This basic starter board gives you great access to the world of Arduino. 20 I/O pins (14 digital, 6 analog) and both USB and DC connections for power. This board uses the 8-bit, AVR, RISC-based ATmega328P microcontroller from Atmel. Built on the 'open-source electronics prototyping platform', and compatible with existing Arduino software lilbraries.

HIGHLIGHTS
• 8-bit AVR RISC-based microcontroller running at 16 MHz
• Connects to a computer via a standard USB cable
• Flexible power source (USB or DC power)
• ICSP header for programming microcontroller
• Compatible with existing Arduino software libraries
• Compatible with the Ethernet and Motor Controller Shields
