HL1602B 16×2 character LCD module with white characters on a blue background, a white backlight, and a 5.0 V supply. Supports 6800 4-bit or 8-bit parallel communication through 16 pins for equipment status displays.

The HL1602B 16×2 character LCD module displays equipment messages, operating values, and status information across two lines of 16 characters. This COB module uses a transmissive, negative STN display with white characters on a blue background and a white backlight, providing a compact text interface for embedded equipment.

Suitable applications include control panels, measurement instruments, and equipment status displays. The module supports 6800 4-bit or 8-bit parallel communication through a 16-pin interface and uses a 5.0 V supply. Integration requires checking the mechanical fit, contrast adjustment circuit, backlight power requirements, and controller initialization against the confirmed module documentation.
