HSM2002A – 20×2 Character LCD Display (STN-Blue Negative) with Parallel Interface

Product Overview

The HSM2002A LCD module offers a 20 characters × 2 lines display configuration, using STN-blue negative transmissive technology to ensure excellent contrast and readability in dim or indoor environments.
It is driven by an HD44780-compatible controller, supporting a 5V single power supply and 8-bit parallel interface for easy integration with common MCUs such as STM32, Arduino, and 8051.
The white LED backlight provides uniform brightness with low power consumption (5V / 40mA).
With a –20°C to +70°C operating range, this module is designed for long-term reliability in industrial and commercial environments.
