PINOUT
BACKLIGHT
Using the LED backlight requires an current source or external current-limiting resistor. Forward
voltage for white LED backlight is 3.0~3.6V. Please take care of derating for T
Attention: Do never drive backlight directly to 5V; this may damage backlight immediately !
The blue display cannot be read without backlight. For direct sunlight we suggest to use the J-type.
