Raspberry PI LCD1602 Add-on is customized for Raspberry Pi interfaces based on LCD1602 display module. With GPIO’s on Raspberry Pi, it can be used to control the contents to be displayed; with software, it can be used to control the backlight for on and off. Buttons on the module can be used to control cursor location on the screen. In addition, electronic brick interface can bring more expanded functions for the Raspberry Pi.
