    This display does not have a current limiting resistor, one should be used when powering the backlight.
    The maximum current for the backlight on this display is 50mA.

    Hello,

    I am using this model for my project  with 3V3 voltage with one TPS61201, http://www.newhavendisplay.com/specs/NHD-C12832A1Z-FSR-FBW-3V3.pdf

    It suffices with one resistor or is it better to use a 3.0V LDO?

    Morning,

    It is typically preferred to supply the displays Typ. Voltage when ever possible, however in your case supplying 3.3V is perfectly acceptable  :)

    Thanks Paul,

    Then I'll used 3V3 for supply and backlight.

    Best regards
