PINOUT
BACKLIGHT
Using the LED backlight requires an current source or external current-limiting resistor. Forward
voltage for yellow/green backlight is 3.9~4.2V and for white LED backlight is 3.0~3.6V. Please take
care of derating for T
Note: - Do never connect backlight direct to 5V; this may destroy backlight immediately !
