The WG12232BP1 is a 122x32 monographic LCD display module. Both the WG12232BP1 and WG12232G share the same outline size of 65.4 x 28.32 mm, a viewing area of 54.8 x 19 mm, an active area size of 48.76 x 14.36 mm, and a diagonal size of 2 inches. This 122x32 graphic LCD module is equipped with the SBN1661G controller IC. It supports a 6800 8-bit parallel interface and a 5V power supply, with a 2KHz internal oscillator.

Both the WG12232BP1 and WG12232G series offer many combinations for LED backlight and LCD mode selection. However, only the WG12232BP1 does not provide an option for a white backlight. If you require a built-in Chinese character library, the WG12232M model is available as an alternative. The WG12232BP1 has a connector instead of FFC, whereas the WG12232G features FFC on the module. The operating temperature ranges from -20°C to +70°C, and the storage temperature is between -30°C and +80°C.
