122x32 Graphic LCM, ST7920 IC, 6800/SPI

Model No. RG12232C3

RG12232C3 is a graphic LCD display series with resolution of 122x32 pixels. RG12232C/C1/C3 series share the same module dimension 59.0×29.3 mm. The additional PCB on this LCD display helps users to save time on developing PCB on their own.

RG12232C/ RG12232C1 adopt IC SBN1661G supporting 6800 interface. RG12232C3 utilizes IC ST7920 supporting 6800/SPI interface and Chinese fonts. The module also has built-in booster +3V as option. We offer a variety of combinations of LED backlight and LCD mode. White backlight is not available for these 3 series.
