This board can be powered via the micro-USB connection with 5VDC voltage. If the board is powered through the Vin pin, a regulated 5VDC must be applied. There is no on-board voltage regulator for higher voltages, which will damage the board. The Yún is also compatible with PoE power supply but in order to use this feature, a PoE module is mounted on the board or a pre-assembled board can be used.

This board is an ideal solution when designing connected devices and Internet of Things (IoT) projects. It is a combination of the power of Linux and the ease of use of Arduino. In addition to Linux commands like the cURL, the user can write own shell and python scripts for robust interactions.
