- Based on Arduino Leonardo, Leonardo & Xbee R3 makes great improvements. The Arduino Leonardo is a microcontroller board based on the ATmega32u4, which has built-in USB communication, eliminating the need for a secondary processor. This allows the Leonardo to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.
- DFRobot Leonardo & Xbee R3 has a XBEE module slot for wireless communication and three sensor pins. Additionally, a 5V D14-D16 expansion port for maximizing ATmega32u4 functions.

I was looking to buy a cheap Arduino clone. I have several offical boards, but this hobby is getting expensive and I wanted some that I could put into production in a more permanent position.
Therefore, I don't mind buying a clone. They're cheap, and mostly of reasonable quality. However, I received a full-blown counterfeit product, including all the official logos. This is something that I usually frown upon, because these boards may be deceiving to novice users. I had to put this to my official Leonardo to spot the differences.
Mind you that the picture shows a true clone (not bearing the Arduino name).
