Diagram — La-e791p Rev 2.0 Schematic

I should check if there's any public information on La-e791p. If not, perhaps create a hypothetical example, using common components found in such revisions. Mention standard components like voltage regulators, microcontrollers, capacitors, resistors. Discuss possible interfaces—USB, I2C, SPI, GPIO. Maybe include a block diagram or a sample section of the schematic. But since actual diagrams can't be included, describe them in detail.
