Arduino Uno, Genuine, ATmega328P MCU, A000066 - Original Board

The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet).It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, anICSP header, and a reset button. It contains everything needed to support themicrocontroller; simply connect it to a computer with a USB cable or power itwith an AC-to-DC adapter or battery to get started. The Uno differs from allpreceding boards in that it does not use the FTDI USB-to-serial driver chip.Instead, it features the Atmega16U2 (Atmega8U2 up to version R2) programmed as aUSB-to-serial converter.This product is the original/genuine product made in Italy (not a clone orreplica)Microcontroller Atmel ATmega328Operating voltage of 5VMaximum supply voltage 6 to 20VDigital I/O pins 14 (of which 6 provide PWM output)DC current per I/O pin 40 mADC current for 3.3V pin 50 mAFlash memory16KB of which 2KB is used by Boot loaderSRAM 2KB, EEPROM 1KBClock speed 16MHzCan be powered via the USB connection or with an external power supply.
