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:
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?
Thanks
I looked at the datasheet from spark fun and it shows this lCD is a 3.3Volt so you may fry it if you hook it up to 5 volts.
VDD1 supply voltage 1 LCD voltage externally
supplied (voltage generator
disabled)
2.7 - 3.3 V
VDD2 supply voltage 2 LCD voltage internally
generated (voltage
generator enabled)
2.7 - 3.3 V
