More info


This comaptible board 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 because it does not use the FTDI USB-to-serial driver chip.

Additional features coming with the REV3 version are:

  • ATmega16U2 instead of 8U2 as USB-to-Serial converter.
  • 1.0 pinout: added SDA and SCL pins for TWI communication placed near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board and the second one is a not connected pin, that is reserved for future purposes.
  • Stronger RESET circuit.

"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 Arduino, moving forward. The Uno is the latest in a series of USB Arduino boards, and the reference model for the Arduino platform.



Excellent and Professional customer service support

Nic from Desensed are very helpful and professional in arduino and electronic. Fast shipping and great product. I can't find any shop better than Desensed. Thanks Desensed.


Unbeatable price and amazing service

I just got another board from this website, with the coupon and free shipping, I says that the guy who sell me this stuff probably earn the least from it. Again, superb service, very good communication and extremely fast delivery, definitely going to buy everything here in the future.

Very happy

I got this board a week ago and I was a bit concerned if it's going to do same job as the original one, price was half the original one.. but life is too short right? I bought it and when it arrived straight way I went and test it. It worked exactly same as the original one, every tutorial on YouTube works as fine as it should... I tried on Ultrasonic sensor, thermistors , servos and even the capacitive sensors, all of them worked as they had to.
