The I/O connector has an unregulated power input (Vin, pin 10). You can provide between 6V and 10V to this input and Pixy2's linear regulator will create the 5V power rail. | The I/O connector has an unregulated power input (Vin, pin 10).

Powering Pixy through Vin (pin 10) can result in more current being available for the RC-servos to use with the pan-tilt unit. Connecting Pixy2 to an Arduino when Pixy2 is being powered through Vin results in **Pixy2 sourcing the power for the Arduino**. This is sometimes preferable to the Arduino sourcing power to Pixy2 because the voltage regulator on some Arduinos cannot handle the current requirements of Pixy and the pan-tilt unit (two RC-servos.) | Powering Pixy through Vin (pin 10) can result in more current being available for the RC-servos to use with the pan-tilt unit.
