![]() You can find here your board warranty informations.ģ2 KB (ATmega328P) of which 0. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. Arduino Uno R3 Specifications It is an ATmega328P based Microcontroller The Operating Voltage of the Arduino is 5V The recommended input voltage ranges from. ![]() 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of USB Arduino boards, and the reference model for the Arduino platform for an extensive list of current, past or outdated boards see the Arduino index of boards.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. 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. "Uno" means one in Italian and was chosen to mark the release of Arduino Software (IDE) 1.0. 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. All of these basic specs are significant upgrades over the previous UNO. 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 R3 and the Leonardo both use the same PCB pin layout, but some of the microcontroller functions are different. In addition, this chip contains 32 kilobytes of SRAM and 256 kilobytes of flash. Microcontroller: ATmega328P-PU Clock Speed: 16 MHz Flash Memory: 32 KB SRAM: 2 KB EEPROM: 1 KB Operating Voltage: 5V Input Voltage: 7-12 V Digital I/O Pin Count: 14 (including 6 for PWM output) Analog Input Pin Count: 6 Dimensions: 2.7 x 2.1 Power Source: USB or external DC power supply Price: 24. 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. Arduino Uno is a microcontroller board based on the ATmega328P ( datasheet). The ATmega328 on the Arduino Uno comes preprogrammed with a bootloader that allows you to upload new code to it without the use of an external hardware programmer.
