Datasheet in PDF format, 363 KB, for the PC0602LRS-XHH-H character LCD module, following the Powertip numbering where 0602 means 6 characters on 2 lines. XHH is the option code and H the revision. The larger file size suggests more drawings or tables than its siblings. Use it to check connector pinout, supply and contrast voltages, backlight specifications and outline before fitting or replacing the display, and compare the label suffix on the actual module so the correct variant data is applied.
