Another copy of the UG-2828GCEAF02 display module datasheet, this one a 1.31 MB PDF with a trailing dash in its name. Content should cover the module interface pins, recommended operating conditions, power-up sequence and mechanical drawing. It is used for checking voltages on the flex cable, confirming the interface mode selected by strap pins, and fitting a replacement. Because several versions of this document circulate, compare revision history pages against the other copies to use the latest data.
