  • 2 Voltage Sources

    Hi, i want to know if is there a problem for connect 2 sources of voltage for uLCD-35DT at the same time. For example connect +5V and GND supply to the header H1, and connect in header H2 the USB cable. Both make a supply for display.
    There's any problem?

    The circuit is in the datasheet...

    They are both isolated from each other, so it will be fine.
