Description
WO13232B is a monochrome COG graphic LCD module made of 132 x 32 dots matrix with metal pinout. This module has the same outline dimension size as WG12232B / WG12232G (with PCB) but with a higher resolution. This COG module is built-in with ST7567A IC; it supports I2C interface, viewing direction 6 o'clock, 1/33 duty, and 1/6 Bias.
The WO13232B is available for FSTN Positive Transflective LCD with a white LED backlight (WO13232B-TFH) and DFSTN Negative (Double film) Transmissive LCD (WO13232B-TDI). This module can be operating at temperatures from -20℃ to +70℃; its storage temperatures range from -30℃ to +80℃. The supply voltage for logic of WO13232B is 2.7V to 3.3V, the typical value of 3V.
