Specification sheet for the PG12232LRU-BNN-B graphic LCD module, stored as a 201 KB PDF. It sits alongside the other PG12232 variants and differs mainly in the option code, which typically designates backlight and display mode. A technician would open it to read the connector pinout, supply and LED backlight ratings, and outline drawing when replacing a dim or dead panel. Measure the backlight current and logic voltage against the listed values, and make sure the suffix printed on the module agrees with this document.
