This document introduces the features and characteristics of the DD-12832XX-1A OLED display module.
These application notes describe the DD-12832XX-1A OLED display module and its evaluation board (EVK). The document provides the EVK schematic, a complete symbol definition for all pins, and detailed timing characteristics for 80‑series, 6800‑series, and SPI interfaces.
It also includes connection diagrams between the OLED and EVK, power‑up/power‑down sequences, usage guidelines, and a recommended initialization routine with sample C code for 8080‑series CPUs.
| VCC | Power supply for panel driving voltage |
