Engineering Notes Before Ordering
Power Design
Check 5.0 V logic supply, VO contrast adjustment, and the 3.5 V typical LED backlight drive requirement before finalizing the host PCB.
Bus Mode Review
The ST7066U function set describes 8-bit and 4-bit MPU bus modes. Confirm host firmware timing and initialization before sample testing.
Variant Confirmation
The related engineering files include DM-LCD1602-424, DM-LCD1602-425, and DM-LCD1602-426. Confirm the exact part number and display appearance with DisplayModule before ordering.
Project Confirmation
Confirm sample availability, lead time, color option, backlight requirement, mechanical fit, and any customization requirement with DisplayModule before volume procurement.
Common Questions Before Sample Evaluation
Which controller IC is used?
The DM-LCD1602-425 datasheet lists ST7066U as the controller IC.
What interface does this 16×2 LCD use?
The module uses a 6800 Series MPU interface with RS, R/W, E, and DB0 to DB7 data bus lines.
Can it use 4-bit communication?
The ST7066U instruction description includes 8-bit and 4-bit MPU bus modes. Confirm your initialization sequence and timing during sample evaluation.
