Description

This board is an Uno R3 compatible version of the latest iteration of the Arduino Uno which is the most popular of the many development boards available for hobbyists.

Package Includes:

  • Arduino Uno Rev3

Specification

  • Supply voltage from 7 V to 12 V
  • Model: Arduino Uno
  • Microcontroller: ATmega328
    • Maximum clock frequency: 16 MHz
    • SRAM: 2 KB
    • Flash memory: 32 KB (5 KB is reserved for bootloader)
    • EEPROM: 1 KB
  • I/O Ports: 14
  • PWM outputs: 6
  • Number of analog inputs: 6 (channels of converter A/C with 10 bit resolution)
  • Serial interfaces: UART, SPI, I2C
  • External interruptions
  • The connected led on pin 13
  • USB A connector for programming
  • DC connector 5.5 x 2.1 mm for power

The Uno R3 operates at 5V which can be supplied via an external power supply or through the USB port connection.  The power source is selected automatically if both are available.  If an external supply is used, it is recommended to use a supply between 7-12V.  Higher input voltages will cause the on-board regulator to work harder and may cause it to overheat.

The attached board pin-out shows the most commonly used functions for the pins, but some pins can support other functions.  Refer the the Arduino documentation for all possible functions for the pins.

This is the original Uno design which uses a DIP processor placed in a socket.  The benefit to this design is that it is easy to replace the processor should the chip become damaged, but it does cost more than the SMD version that we also sell.  It also has the same Atmega16U2 USB converter as the original Uno for maximum compatibility.
