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of USB Arduino boards, and the reference model for the Arduino platform for an extensive list of current, past or outdated boards see the Arduino index of boards. The Uno board and version 1.0 of Arduino Software (IDE) were the reference versions of Arduino, now evolved to newer releases. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6. 'Uno' means one in Italian and was chosen to mark the release of Arduino Software (IDE) 1.0. The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet). 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. Technical specifications Arduino Uno R3 board with ATmega328P MCU in DIP-28 package Microcontroller (MCU): IC: Microchip ATmega328P 9 Clock Speed: 16 MHz on Uno board, though IC is capable of 20MHz maximum at 5 Volts Flash Memory: 32 KB, of which 0. It has 14 digital input/output pins (of which 6 can be used as PWM outputs). This versatile microcontroller is equipped with the well-known ATmega328P and the ATMega 16U2 Processor. 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 Rev3 is a microcontroller board based on the ATmega328 (datasheet). Arduino UNO R3 1 / 1 3 Arduino UNO R3 Modied: Product Reference Manual SKU: A000066 Description The Arduino UNO R3 is the perfect board to get familiar with electronics and coding. 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. 2x LCD Contrast, Atmega328P is the default chip of Arduino UNO, it has a 32K bytes flash memory, 1k bytes EEPROM, 20 MIPS. Arduino/Genuino Uno is a microcontroller board based on the ATmega328P (datasheet). X1000 32-bit 329681-001US Galileo Datasheet arduino uno r3: arduino uno r3.
