Usage Notes:

bullet

VIN supply voltage should not exceed ~5 VDC. 

bullet

When powered by USB, VIN is 5 VDC.

bullet

Powering the Quickstart directly with a 9V battery would exceed the backlight current limit and damage the display.

bullet

It is probably safe to use power from 4 AA or AAA cells though as that is about 6 V but goes through a diode, which would drop it a bit.
