Category: Graphic LCD

Description

The WG12232A is a monochrome 122×32 graphic LCD display module with a PCB board, featuring an outline size of 84 x 44 mm and a viewing area size of 60 x 18 mm, delivering clear and concise graphic displays. This 122×32 graphic LCD display is built with the SBN1661G controller IC.

It supports a 6800 8-bit parallel interface and defaults to a 5V power supply, with an optional version of the negative voltage generator for 3V. The WG12232A model comes with internal oscillation capability. For customers who require external oscillation of 2KHz, the WG12232C model is available. If the customer requires support for Chinese fonts, please choose the WG12232L model series.

The WG12232A graphic LCD display module series comes with a PCB board, eliminating the need for customers to develop additional PCB boards themselves. Four screw holes are designed on the PCB to facilitate easy installation of the module on the application product. This 122×32 LCD module can operate at temperatures ranging from -20℃ to +70℃, with storage temperatures ranging from -30℃ to +80℃.
