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 2014 designed board uses SMD hardware which reduces the cost but has the same functionality. With more board real-estate there is a new header section for key IOs such as UART I2C and Power.

USB cable included. These devices have the CH340 chip - drivers for Windows and Mac are widely available.


  • This generic model 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

Customer Reviews

  1. Review by Tek verified purchaser

    I like the price. Not sure why it is cheap, possibly because it may not have pull-up resistors built into digital IOs , but works perfectly for me using analog inputs and digital as outputs. Bargain :) (Posted on 17/08/2017)

  2. Review by Monty verified purchaser

    Arrived as described, works perfectly. (Posted on 26/05/2017)

  3. Review by Chris verified purchaser

    A great, cheaper alternative to the Arduino Uno. But found the lack of printing on the headers a bit of an inconvenience. (Posted on 4/05/2017)

  4. Review by James verified purchaser

    Works exactly as expected. (Posted on 13/02/2017)

  5. Review by Michael - Great low cost Uno verified purchaser

    Have had no problems with 4 of them in use now. The extra IO Pin access are a bonus compact projects. (Posted on 2/02/2016)

  6. Review by Warren verified purchaser

    Well built unit and works exactly as promised. (Posted on 1/02/2016)

  7. Review by James - Good cheap unit verified purchaser

    This is a good little China-duino. You will need to grab some extra drivers for it, but that was reasonable straight forward. There are a few differences from a stock Arduino, but all of them good. It works the same without breaking the bank. (Posted on 6/12/2015)
