Can I run the LCD-16x2-black on 3.3V?
Do I need to do anything special to make it work with 3.3V?

Thank you for any suggestions

Kyle,

There are many LCD's that can run on 3.3V, some down to 2 Volts and lower, this isn't one of them, save youself alot of headaches and get a 3.3V display. Using a charge pump/switcher to raise the voltage will add noise to your circuit and the accelerometer will not like it.
