We expect that most Pixy2 users will either power Pixy2 through the USB cable/​connector or though the Arduino cable (I/O connector). These two choices are the simplest, but here are all available power options:
  
-  - Power Pixy through the USB cable/​connector (regulated 5V) +  - Power Pixy2 through the USB cable/​connector (regulated 5V) 
-  - Power Pixy through the I/O connector (regulated 5V) +  - Power Pixy2 through the I/O connector, pin 2 (regulated 5V) 
-  - Power Pixy through the power connector (unregulated 6V to 10V)+  - Power Pixy2 through the I/O connector, pin 10 (unregulated 6V to 10V)
  
-Note: you can have both the Arduino cable **and** the USB cable plugged into Pixy simultaneously without any bad things happening. In fact, this is very useful when you want to do a quick check to see what Pixy sees through PixyMon, while Pixy is connected to your Arduino (in situ, so to speak).+Note: you can have both the Arduino cable **and** the USB cable plugged into Pixy2 simultaneously without any bad things happening.

-When you plug Pixy into your computer via USB cable, ​Pixy 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 the pan/tilt mechanism) as long as the USB cable is kept somewhat short (less than 4ft is best).+When you plug Pixy2 into your computer via USB cable, ​Pixy2 is powered through the regulated 5V provided by the USB port.

-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!**+The I/O connector is marked "​J2"​ on Pixy2's PCB. Pin 2 of the I/O connector can accept 5V for powering ​Pixy2.

-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.
