The 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 analogue 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.

This is the latest revision of Arduino Uno and features stronger reset circuit and 16U2 microcontroller instead of the 8U2.

USB cable included.

Features:

  • This board is a generic model, built on the Uno design by Arduino and is completely compatible with the genuine Arduino® Uno. We also stock the genuine made in Italy version.
  • Microcontroller: ATmega328
  • Operating Voltage: 5V
  • Input Voltage (recommended): 7-12V
  • Input Voltage (limits): 6-20V
  • Digital I/O Pins: 14 (of which 6 provide PWM output)
  • Analogue Input Pins: 6
  • DC Current per I/O Pin: 40 mA
  • DC Current for 3.3V Pin: 50 mA
  • Flash Memory: 32 KB (ATmega328) of which 0.5 KB used by bootloader
  • SRAM: 2 KB (ATmega328)
  • EEPROM: 1 KB (ATmega328)
  • Clock Speed: 16 MHz

    I'm a little disappointed. Our application is to build a time-sensitive instrument and the Ceralock resonator in the Genuine Uno is not adequate. When I saw "a 16 MHz crystal oscillator" in the Uno R3 (Arduino-Compatible blurb I grabbed a one.
    However the crystal is for the USB controller, and the processor still uses a Ceralock Resonator.
    So IMHO the blurb is a little misleading.
    Having said all this, the device I received certainly looks well made and is compatible to the Genuine Uno, but neither are suitable for my task.

    Straight out of the packet and into the robot. Works like a charm. A very affordable option for duplicate UNO boards.

    The QC is not quite as good as a DF Robot UNO but certainly acceptable. (Posted on 7/09/2016)

    This is exactly what it says on the tin, and it certainly works. I've had a little trouble interfacing it to a 3.3v device I'm trying to use, but that can be solved with a level translator.

    It is a full UNO for less than a pack of smokes. Maybe its time to quit smoking and buy 7 of these a week. Great product for the price. Definitely not the build quality of a official Arduino but does exactly the same thing so great as a learning tool and also when you are building toys for your kids.

    Recommend this fully. (Posted on 8/10/2014)

    i purchased a similar product from Jaycar called freetronics .. i like jaycar products quite a lot .. but this unit is more reliable and i've had no failures.. it's used to control a solar pump and blower pump for a spa .. it works beautifully :) no doubt i'll purchase more in near future ... for many other projects..

    Core great job!! (Posted on 12/07/2014)

    Fit, form and function of the original at a much more reasonable price. I've been using a few of these in some short term projects and they haven't missed a beat. Very happy.

    Top marks for great service and speedy delivery. (Posted on 9/07/2014)

    I bought two when I found the CORE website and both are in full service. One powers a data logger collecting corrosion information, the other schedules a display for advertising. Keep them coming Graham. Thanks

    It was the cheapest I could find in Australia, in fact I found some Arduinos for 4 times that price! And this one is just perfect. As described, very fast shipment and great costumer support. Recommended! (Posted on 3/11/2013)

    Necessity is the mother of invention and I have the need for the basis of a data logger...........my generation made things themselves.
    This clone fitted the bill exactly allowing me to experiment and to achieve the required outcome. I bought two and they worked as described directly out of the packet. The cable per item was a bonus. Thanks and I will be back. The ease of ordering, checking and mail receipt is excellent. Support Aussy entrepreneurs. Thanks again. (Posted on 20/09/2013)
