    I have a 7-segment display (has two decimal point on each side) the only numbers on it are M72/K312B. I cannot find any datasheets for it! Can anyone help me?

    Don't worry too much about not being able to find a datasheet.

    If you have a meter with a diode test function, you can quickly determine which pins will light up which segments, and which pin(s) are the common cathode or common anode connections.

    It is a common anode
    pin 3 and 14 are high, the rest will be low inputs
