This product is retired, please consider our Seeeduino V4.2as your alternative choice.
If you are an old friend of Seeed, you may know that Seeeduino is one of Seeed’s most popular products. Ever since it was born in 2009, Seeeduino has been upgraded many times and the most recent one is Seeeduino V4.2, the best Seeeduino version ever. The reason why we recommend Seeeduino V4.2 is because this is an Arduino compatible board while integrated many good features that Arduino Uno doesn’t have. Such as the grove connectors, the input voltage select button. And it is also a very reliable and good looking board. Please refer to the page of it for more information.
The Arduino Uno Rev 3 is a microcontroller board based on the ATmega328 (datasheet). 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 Arduino boards is that the Uno 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 Arduino, moving forward. The Arduino Uno board rev 3 is the latest in a series of USB Arduino boards, and the reference model for the Arduino platform.
Operating voltage: 5V
Input voltage (recommended): 7-12V

What is the weight?
Hi,About 30g. I weighed it just now,28.30g
Can I use arduino UNO R3 instead arduino duemilanove in GPRS shield proyects
yes, uno r3 is similar as arduino duemilanvoe of the same ship mega328p
Is their any kit for Arduino UNO R3? However if I buy Arduino UNO R3, does it has the cable which connects the Arduino into the computer using a USB port?
Sorry but it's not included. You might want to use a printer USB cable (type B) or get one here: http://www.seeedstud
Hi Everyone, I am new to arduino. I was developing a product which involves a Android device connected to the Arduino board. Initially I thought of using a ADK Board. But since its too costly, the alternatively we found out that Arduino Uno can be used
Sorry???Arduino Uno can not directly connect to Android device .If you want to control your Arduino device in your project , you can use a bluetooth module , and control it via Android bluetooth serial APP .
does this product made in china?
No,it is official Arduino , made in ITALY.
I just ordered an Arduino starter kit. I was wondering how can I find an arduino compatible 8x8 (or bigger) LED matrix? Is that possible to use 64 (or more than 64) LED's with arduino?
It it possible to ues more than 64 LED with arduino,depend on your LED drive.
is this chinese version?
No, it's from Italy.
When will the Arduino Uno be available here again?
It would be soon, click"Notify me"that would inform you when we available.
