Arduino – ArduinoBoardUno

The Arduino Uno is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. 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 differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega8U2 programmed as a USB-to-serial converter.

“Uno” means one in Italian and is named to mark the upcoming release of Arduino 1.0. The Uno and version 1.0 will be the reference versions of Arduno, moving forward. The Uno is the latest in a series of USB Arduino boards, and the reference model for the Arduino platform; for a comparison with previous versions, see the index of Arduino boards.

Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.

  1. Do you have any plans for creating a “programmable” USB/Serial interface board? – just like the FTDI one you sell, but able to emulate MIDI, Mouse, Keyboard, Joystick etc… ?

    I would find that really useful, and it would mean that I could equip all my Boarduino projects with some UNO goodness.

  2. Has anyone else noticed that the chip is the wrong way round in either this image (above) or the one on the Arduino site – insertion proof chips, what will they think of next? 🙂

  3. Steve: unless they changed the chip around on the design, thats they way it is on my Duemilanove, yah looking at the reference design board files it is inserted correctly, with the half moon facing away from the power and USB connectors
