## Description

The R3 Uno Card is an ATmega328-based microcontroller board consisting of 14 digital input / output pins (6 of which can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power plug, an ICSP header, and a reset button   It contains everything needed to support the microcontroller; just connect it to a computer with a USB cable or power it with an AC-DC adapter or battery to get started   New features1.0 pinout: Adding SDA and SCL pins near the AREF pin and two other new pins placed near the RESET pin, the IOREF which allows the screens to adapt to the voltage provided by the board. In the future, they will be compatible both with the card that uses the AVR, which works with 5V and with the Arduino Due that works with 3.3V.RESET circuit stronger;Atmega 16U2 replaces the 8U2   SpecificationMicrocontroller: ATmega328Operating voltage: 5VInput voltage (recommended): 7-12VDigital I / O: 14 (6 of which provide PWM output)Analog input pins: 6DC current per I / O pin: 20 mADC current for the 3.3 V pin: 50 mAFlash Memory: 32 KB (ATmega328) of which 0.5 KB used by bootloaderSRAM: 2KB (ATmega328)EEPROM: 1 KB (ATmega328)Clock speed: 16 MHzLength: 68.6 mmWidth: 53.4 mmWeight: 25g

## Features

- Uno R3 card: a microcontroller board based on the ATmega328     Contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-DC adapter or a battery     The Uno R3 differs from all previous cards in that it does not use the FTDI driver as a serial USB driver     Instead, it features the Atmega16U2 programmed as a USB-to-serial converter    ›See more product details
