Description
The 16×2 LCD Display 1602 Green is a compact and easy-to-use character LCD module designed for displaying alphanumeric information in embedded and electronics projects. It features 2 rows with 16 characters per row, making it suitable for displaying sensor readings, menus, status messages, counters, and other data.
Each character is formed using a 5×8 pixel matrix, providing clear and readable text. The display uses an SPLC780D1 or equivalent controller and supports both 4-bit and 8-bit parallel communication, making it compatible with Arduino and a wide range of microcontrollers.
The built-in green LED backlight improves visibility and gives your project a clear, professional display appearance.
