The Uno board is the first of a series of USB Arduino boards and the reference model for the Arduino platform see the Arduino index of boards for a comprehensive list of current, historical, or obsolete boards. The Uno board and Arduino Software (IDE) version 1.0 were the reference versions of Arduino, which have since progressed to later releases. The name “Uno” means “one” in Italian and was selected to commemorate the launching of the Arduino Software (IDE) 1.0. You can tamper with your Uno without fear of doing something wrong in the worst-case scenario, you can replace the chip for a few dollars and start over. It contains 14 digital input/output pins (of which 6 may be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator (CSTCE16M0V53-R0), a USB connection, a power connector, an ICSP header, a reset button.Īrduino Uno R3 It includes everything needed to support the microcontroller simply connect it to a computer through USB or power it with an AC-to-DC converter or battery to get started.

Performance between the boards are the same. The SMD version simply has the ATmega chip surface mounted on the Arduino board making it more difficult to replace. Click here if you're looking for the SMD version. This version has the ATmega chip in a through-hole, so the chip can be easily replaced. Its 32 kB Flash memory gives it enough room for most sketches/code to upload into the Arduino Uno. With a 16 MHz clock speed, it's able to perform instruction commands efficiently. Instead, it features the Atmega16U2 (Atmega8U2 up to version R2) programmed as a USB-to-serial converter.
The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip.
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. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button.
