 The I/O connector is marked "J2" on Pixy2's PCB. Pin 2 of the I/O connector can accept 5V for powering Pixy2. This is convenient when you want to power Pixy2 through the Arduino cable (ie, by hooking up the Arduino cable, your Arduino is powering Pixy2, assuming your Arduino is suitably powered.) Or you can make your own I/O cable for Pixy2 communication/power, **but be careful! Pin 2 and the ground pin (pin 6) are not reverse-polarity protected. Get the power backwards and Pixy2 is a goner. For good!**
-Note also, ribbon cables can drop. So it's unlikely you can power Pixy2 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.
