    About Serial Enabled 16x2 LCD - Red on Black 3.3V
    sku: LCD-09068
    It says “Note: This is a 3.3v Serial LCD. Connect to a 3.3v power source."
    But, when I opened the package, it says 5V on the
    little serial board terminal. (as shown on in the above pic).
    The main LCD pcb has a 3.3V label on it.
    My guess is, that little serial board will work with either 3.3 or 5V, but my LCD is only good for 3.3V..
    Am I right?

No public wish lists :(
