    Why do I get power out of the VDD port with only RX and GND hooked up? I have a 5V rail that I use to power everything on my board - and when I added this SerLCD I now have a bridge between the arduino power and my 5v line … which I dont want. Can I add a diode to the VDD to stop reverse voltage from powering my board?

No public wish lists :(
