A Beginner's Arduino Guide/Where to get Arduino

There are two types of Arduino controllers:

Genuine Arduino Controllers

These controllers usually cost about $25 USD. Most of the funding goes to support the Arduino organization. We strongly encourage you to purchase at least one Genuine Arduino or make a contribution to the project.

Genuine controllers often work best with the Arduino software. They use common serial controller chips such as the FTDI chip that have certified signed drivers for both the PC and Mac.

Arduino Clones

These are typically around $5, however you can find some Arduino Nano versions for as little as $2.27 (includes shipping). EBay is a popular place to purchase Arduino controllers, however be warned that many of the suppliers are in Hong Kong and China. Allow one or two weeks for shipping.

The lower-cost Arduino Clones use a lower-cost CH340D serial interface chip. The drivers for these chips are not included in the Arduino IDE. You must install these drivers manually.
