Revision C of the PG9732 family datasheet, an 88.3 KB PDF. The model number suggests a 97 by 32 dot graphic LCD module, with this document covering features shared across its variants. Look here for the connector pinout, logic and LCD voltages, controller timing and mechanical size. Several revision letters of the same family exist, so check which matches the date or marking on your part. Before replacing a module, confirm the suffix printed on it, since backlight wiring can vary.
