The Keyestudio 1602LCD Keypad Shield combines a 1602 LCD display with six integrated buttons, designed for seamless stacking on the Keyestudio UNO R3 control board. It supports both 8-bit and 4-bit communication modes with the UNO R3, defaulting to the efficient 4-bit mode. The six buttons include five control keys and one reset button, providing convenient user input options for interactive projects.
The Keyestudio 1602LCD Keypad Shield features five control buttons—Select, Up, Down, Left, and Right—plus a reset button located beneath the LCD. The five control buttons share a single analog input (A0), allowing button status monitoring through one Arduino pin. Note that simultaneous button presses cannot be detected. Additionally, the shield includes a potentiometer to adjust the LCD backlight, providing customizable display brightness for enhanced usability in projects. This shield simplifies display and control integration, making it ideal for advanced embedded system development.
