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 a >+25°C. Note: - Do never connect backlight direct to 5V; this may destroy backlight immediately ! - Blue-white displays do always need a backlight for contrast (min. 5mA).

Note: In contrast to many other dotmatrix lcd modules input is supplied with VDD level here ! CREATING YOUR OWN CHARACTERS All these character display modules got the feature to create 8 own characters (ASCII Codes 0..7) in addition to the 240 ROM fixed codes. 1.) The command "CG RAM Address Set" defines the ASCII code (Bit 3,4,5) and the dot line (Bit 0,1,2) of the new character. Example demonstrates creating ASCII code $00. 2.) Doing 8 times the write command "Data Write" defines line by line the new character. 8th. byte stands for the cursor line. 3.) The new defined character can be used as a "normal" ASCII code (0..7); use with "DD RAM Address Set" and "Data Write".

Additionally to that 8 more characters can be defined individually.

For that solder link 4/8 has to be opened and closed to SPI side. Specification for serial operation mode is written down in user manual for KS0073: http:/ /www.lcd-module.de/eng/pdf/zubehoer/ks0073.pdf ADAPTOR PCB The adaptor pcb EA 9907-DIP is made for a quick function test for all DIP modules. This interface board provides the standard dotmatrix pinout with 1x14, 1x16, 2x7 and 2x8 pins (0.1" pitch). all dimensions are in mm ATTENTION handling precautions!
