Hi I am using this lcd, but I want to solder it permanently rather than using a breadboard, however I am getting mixed thoguhts as to whether the VCC line can and should/should not be 5v.
This diagram from the quick start guide says its ok - and thats the one Ive been using, however if Im going to make it permanent I want to know whats best:http://sfecdn.s3.amazonaws.com/tutorialimages/GraphicLCDLandingPage/LCD2.jpg
Thats shows 5v to vcc. Should it be 3.3v for better care of the lcd, or should I connect it througha resistor? I have the leds on a 3.3v supply with a resistor in place.
If I should be using a resistor, what size should I use?
