    Re: Resistive touch screen datas

    Am using 15 inch resistive touch screen. 1 and 3 resistance value is 530 ohms (Y+ , Y-)
    2 and 4 resistance value is 300 ohms (X+ , X-)

    1 and 3 resistance value is 530 ohms (Y+ , Y-)
    2 and 4 resistance value is 300 ohms (X+ , X-)

    This pin numbers are correct or not? Touch screen model - ST-151001 (ST-008)

    Hi,

    Just follow the traces ... it's quite obvious.
    (I don't have one by hand, to do this for you)

    Re: Resistive touch screen datas

    It's not showing correct value. Pressure =0.
