- | 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. | ||
