USB Cable for Arduino Uno, USB Type-A to Type-B (Data Sync and Power)

Every Arduino Uno needs a cable that can carry data as well as power, and this one does both. Plug the square Type-B end into your Uno and the USB-A end into your computer, then open the Arduino IDE and upload your sketch.

This is the same connector used on most printers, so the cable is easy to mistake for one. Many phone chargers do not use it at all, so having a spare in your project box saves you from a stuck project when the original cable goes missing.

Besides the Uno, the cable also works with the Arduino Mega and other boards that have a Type-B port.
