HSM2402A – 24×2 Character LCD Display (STN Yellow-Green Positive) with Parallel Interface

Product Overview

The HSM2402A is a 24 characters × 2 lines STN LCD display that offers clear text presentation and stable contrast in diverse lighting environments.

It adopts a yellow-green positive transflective mode, making it readable under natural light and backlit conditions.

Driven by an HD44780-compatible controller, this module uses a 5V single power supply and a standard 8-bit parallel interface, ensuring broad compatibility with MCUs such as STM32, Arduino, and Raspberry Pi.

Its Y-G LED backlight ensures consistent brightness and low power consumption (5V / 40mA).

With an operating range from –20°C to +70°C, the HSM2402A is widely used in industrial control panels, laboratory instruments, and automation systems.
