eptheca Posted December 22, 2016 Report Share Posted December 22, 2016 (edited) I am finally building my old sammichFM kit :) The LCD that came with it is an Orient Display FSTN Negative red On the PCB there is an option for "High-power" backlight (250mA) The standard configuration is for "Low-power" (25mA) The paper for the LCD says: Max V= 4,1 and that the forward current for the RED backlight is 210mA Which setting should I use? I think it is a bit dark/dim, or maybe it's the type of LCD. Is it safe for this LCD to use the High-power setting?
