 ==== USB cable/connector ====
-When you plug Pixy2 into your computer via USB cable, Pixy2 is powered through the regulated 5V provided by the USB port. It is also possible to power small RC servos through the USB cable (like the ones in [[https://pixycam.com/pixy2-pan-tilt-kit/|the pan-tilt mechanism]]) as long as the USB cable is kept somewhat short (less than 4ft is best).

 ==== I/O connector ====
-The I/O connector is marked "J2" on Pixy's PCB. Pin 2 of the I/O connector can accept 5V for powering Pixy. This is convenient when you want to power Pixy through the Arduino cable (ie, by hooking up the Arduino cable, your Arduino is powering Pixy, assuming your Arduino is suitably powered.) Or you can make your own I/O cable for Pixy communication/power, **but be careful! Pin 2 and the ground pins (pins 6, 8 and 10) are not reverse-polarity protected. Get the power backwards and Pixy is a goner. For good!**

-Note also, ribbon cables have poor current-carrying ability. So it's unlikely you can power Pixy through the I/O connector via ribbon cable **and** have enough power left over for controlling RC servos. The voltage will drop too much across the ribbon cable. Nothing bad will happen, if you try this but the servo will likely malfunction.
