  Package Includes:  

• 1 x Arduino Leonardo without Headers

This version of the Leonardo does not come with any headers attached, making it ultra-thin and lightweight. With built-in USB communication, it eliminates the need for a secondary chip and can appear to a connected computer as a mouse and/or keyboard, in addition to a virtual (CDC) serial/COM port. Please note that this board is only supported in the latest Arduino IDE 1.0.1 and above, so you may need to update your IDE.
