WO1602I3 and WO1602I5 are two models of 16 characters by 2 lines of COG LCD P/N WO1602I with PCB board on module. WO1602I3 and WO1602I5 are built in with ST7032i IC; it supports I2C interface. The advantage of WO1602I3/WO1602I5 is having circuit layout on PCB board and with screw holes which make modules can be fixed on customers’ applications easily. Also, there are three kinds of connector pitch sizes of 2.54mm (default), 1.0mm and 0.5mm for options.

The supply voltage for logic (VDD) of WO1602I3 is 3.3V; as to the WO1602I5 is 5V, 1/16 duty circle, 1/5 bias. The module can be operating at temperatures from -20℃ to +70℃; its storage temperatures range from -30℃ to +80℃. WO1602I3 and WO1602I5 are available in FSTN positive Transflective LCD and with White LED backlight; please contact us if you need different types of LCDs or LED combinations.
