A000066 Arduino Uno is a microcontroller board based on the ATmega328. It has 14 digital io pins, 6 analogue 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. The Uno differs from all preceding boards in that it does not use the FTDI USB to serial driver chip. Instead, it features the ATmega16U2 programmed as a USB to serial converter.
Microcontroller Atmel ATmega328 Operating voltage of 5V Maximum supply voltage 6 to 20V Digital I/O pins 14 (of which 6 provide PWM output) DC current per I/O pin 40 mA DC current for 3.3V pin 50 mA Flash memory16KB of which 2KB is used by Boot loader SRAM 2KB, EEPROM 1KB Clock speed 16MHz Can be powered via the USB connection or with an external power supply
