#153264 - 5v for contrast Responding to: ???'s previous message |
I've talked with the folks at Crystalfontz.com, and the majority of their modules will work just fine at 3.3v.
However, like Jerson mentioned, you still ~4v on the contrast pin, so you need either a 5v supply, or a negative supply. |
