Combined datasheet for the PG12864 graphic LCD module, with the A and K variants indicated in its name, provided as a 57.2 KB PDF. The base number denotes a 128 by 64 dot matrix, and the sheet likely lists pinout, voltages, timing and outline for both versions. Technicians use it to identify connector pins, set contrast drive, and confirm whether a replacement fits. Since one document spans two variants, read carefully which tables apply to A and which to K before wiring.
