PDF datasheet, 141 KB, for the PC1602LRS-DSO-H character LCD module, which the 1602 code marks as a two-line, sixteen-column panel. DSO-H is the variant suffix within the LRS series. Typical material includes pin assignment, supply ranges, contrast drive, backlight current and polarity, command timing and a dimension drawing. A repair technician uses it to measure the right pins on an unresponsive display and to judge whether a different 1602 module can be fitted in its place.
