Arduino Uno Development board (Original Arduino)

Arduino development board based on the 16Mhz, 8-bit, Atmega328 with 32KB flash memory. Great board for hacking!

Arduino Uno is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, 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.. You can tinker with your UNO without worring too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again.

"Uno" means one in Italian and was chosen to mark the release of Arduino Software (IDE) 1.0. The Uno board and version 1.0 of Arduino Software (IDE) were the reference versions of Arduino, now evolved to newer releases. The Uno board is the first in a series of USB Arduino boards, and the reference model for the Arduino platform; for an extensive list of current, past or outdated boards see the Arduino index of boards.

This board has the following specifications:

• 14 general purpose I/O pins (40mA), 6 with PWM
• 6 analog input pins
• 16mhz, 8-bit microprocessor (Atmega328)
• USB header (Standard B-type)
• 6-20V input voltage
• 32KB Flash memory, 2KB SRAM, 1KB EEPROM
