Hi. I’ve got a VMA412 2.8" LCD display. I have two questions:
The display has pins marked 5V and 3.3V. Do I need to power both of them or is this there to let me choose to run the display from either 5V or 3.3V?
Does this display have a built-in character generator? Ie. if I send “A” down the serial line, will it print “A” on the display or do I need something like the Sparkfun LCD Serial Backpack to make this work?
