Technical data sheet for the DS-LCDD3 micro-sized LCD serial interface module from Intelligent Display Solutions.
The DS-LCDD3 is a compact 47 × 26 mm module that provides RS‑232 serial control of standard LCD panels (16×2, 20×2, 40×2, 20×4). It includes on‑board regulation for 5 V or 8‑15 V supplies, adjustable backlight brightness, selectable baud rates and line counts, and can be programmed via a Microchip PIC flash controller.
The document details power requirements, connector pin‑outs for SIL and DIL LCDs, command codes for backlight, baud rate and cursor control, electrical characteristics, programmable I/O pins, and mechanical dimensions. It also contains conformity declarations for commercial, residential and light‑industrial use.
