Attention Mac Users:
Please visit the following link to download the proper FTDI VCP driver before use:


What You Need

●      Arduino Software (

●      USB to mini USB cable

●      PC/Mac with a USB port


Uploading Your First Sketch

1.     Get the Arduino software if you have not already

a.     Download from

b.     Unzip the zip file to somewhere like C:\ (on Windows), so you will end up with a folder like C:\arduino-1.0.1

2.     Prepare for serial communication

a.     Connect the mini USB end of the cable into the board

b.     Connect the other end of the cable into a USB port on your PC/Mac

c.     If your computer prompts for drivers, point it to the “drivers\FTDI USB Drivers” subfolder of the Arduino software, e.g. “C:\arduino-1.0.1\drivers\FTDI USB Drivers”

d.     You should now see the LED labeled ON near the reset button light up

3.     Load the sketch

a.     Open the Arduino software

b.     Open the LED blink sketch: File menu > Examples > Basics > Blink

c.     Select the Arduino Uno.  (IMPORTANT: If your sketch does not load properly using this selection, please select Arduino Duemilanove or Nano w/ ATmega328.  It was brought to our attention that some of our UNO R3 boards may have been loaded with this bootloader instead (we are embarrassed).  Functionally, it is the same so no real concerns.  Please accept our apologies!!  If you have any concerns, please email and you will be looked after!)

d.     Select the serial port: Tools > Serial Port

This is the serial port for the board’s built-in FTDI. If you do not know which one this is, you can find out by going into Device Manager > Ports (COM & LPT), and look for a “USB Serial Port (COMx)”

e.     Upload the sketch: File > Upload to I/O Board

f.      Wait for the “Done uploading” message in the bottom blue status bar

4.     The LED labeled L near pin 13 should now blink slowly

5.     Congratulations! You have successfully uploaded your first sketch to your board.
