PINOUT
BACKLIGHT
Using the LED backlight requires a 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
a
>+25°C
Attention: Do never drive backlight directly to VDD; this may damage backlight immediately !
The blue display cannot be read without backlight. For direct sunlight we suggest to use the J-type.

TABLE OF COMMAND (SSD1803)
SERIAL MODE SPI
Factory set for interface is parallel with 4 bit or 8 bit data bus. Alternative module can be programmes
with serial data stream. For that solder link SPI has to be closed. Harware specification for serial
operation mode is written down in user manual for SSD1803:
http://www.lcd-module.de/fileadmin/
eng/pdf/zubehoer/ssd1803_2_0.pdf. Software for initialisation and programming keeps the same.
