2.2"TFT LCD - HY-TFT220 Voltage Level?
Posted: Mon Jun 25, 2012 8:38 pm
Hello,
I have a HY-TFT220 laying arround here, but i'm a bit confused.
There is a 5V input on the board, and on this link it looks like the LCD is directley connected to a arduino (5v i think?).

But the datasheet of the HY-TFT220 says that the operating voltage is 3.3v.
So, my question is: Is there a level converter onboard?, can I just use 5V? or do I use 3.3v for the logic signals?
Thanks in advance,
(Sorry for the bad english)
