1602 LCD Keypad Shield with Blue Backlight for Arduino A compact shield that combines a 16x2 character LCD and a fivebutton keypad for fast, reliable user interfaces on Arduino compatible boards. Designed for quick integration, clear readout, and simple menu navigation during development and prototyping. Key benefits Clear visual feedback: 16 characters by 2 lines with a blue LED backlight for good contrast and readability in varied lighting. Integrated input and display: Five tactile buttons provide directional and select input without extra wiring, saving time and I/O pins. Easy to integrate: Plugs directly onto standard Arduino headers and works with common Arduino display libraries for rapid setup. Compact prototyping solution: Shield form factor keeps your project tidy and portable while adding a functional user interface. Reliable performance: Sturdy PCB and proven character LCD technology for consistent text display and responsive button input. Main features Function: Character LCD display for text output plus builtin fivebutton keypad for user input and menu control. Display size: 16 columns by 2 rows, standard 1602 format for status messages, prompts, and simple graphics using custom characters. Backlight: Blue LED backlight for improved visibility in low light. Compatibility: Designed to mount directly on Arduino compatible development boards with standard shield headers; compatible with common Arduino display libraries and example code. Interface: Standard character LCD control signals and keypad wired for easy reading from a single analog pin using a resistor ladder, minimizing pin usage. Power: Operates from typical 5V microcontroller power rails. Materials: Standard PCB and LCD module construction for regular hobby and prototyping use. Practical applications Menudriven projects: Build configurable menus for device settings, sensor thresholds, or mode selection without extra wiring. Robotics and automation: Display status messages, battery level, and navigation options while controlling systems with the integrated keypad. Prototyping and education: Teach or learn microcontroller user interfaces by combining display output and button input in a single, plugon module. Why choose this module This 1602 LCD keypad shield provides a straightforward way to add both display and input to Arduino compatible projects. It reduces wiring complexity, speeds up development, and delivers clear, reliable text readouts with a builtin user control panel. Compatibility note Designed for use with Arduino compatible development boards that support standard shield headers and 5V logic. Works with common Arduino display libraries for quick integration.
