Description

The 16×2 LCD module uses the HD44780 driver (or compatible) and provides a simple way to display text and basic symbols. It supports both 4-bit and 8-bit parallel communication and can be interfaced with microcontrollers via direct GPIO or using an I2C backpack for simplified wiring. Ideal for menus, sensor readings, and status messages, it’s a staple in embedded systems and IoT projects.
