Compact LCD1602 character display with integrated keypad and I O expansion for rapid prototyping and embedded projects Why this module helps you get results Adds a clear 16 by 2 character display together with a multi button keypad so you can present information and accept user input with one module. Saves board space and wiring by mounting directly as a shield on compatible development boards, reducing assembly time and wiring errors. Makes simple menus, status displays, and on device controls possible without needing a separate display and input circuit. Key benefits at a glance Simple human interface: 16 by 2 character LCD for readable text output plus an onboard keypad for navigation and selection. I O expansion: extra input and output lines routed to headers so you can connect sensors switches or indicators without using additional breakout boards. Plug and play form factor: designed to install directly onto standard microcontroller development boards that accept shield style modules for fast integration. Low complexity integration: works with common character LCD libraries and simple digital input routines so you can focus on application logic rather than driver development. Durable construction: printed circuit board with tactile keypad switches and a standard character LCD module for reliable daily use. Function and performance Display: 16 columns by 2 rows of character text for status messages, menus, prompts and values. Input: integrated keypad provides tactile controls for menu navigation and user entry. Expansion: additional I O pins are exposed on the board to extend your project without extra wiring harnesses. Power and signal: designed to operate from common 5V logic levels used by most hobby and education microcontroller boards. Readability: character LCD offers clear text output for short messages and numeric readouts. Compatibility and sizing Compatible with shield style microcontroller development boards including Arduino Uno and similar form factor boards. Check pinout compatibility before installation. Compact shield form factor mounts directly to the host board to keep your project tidy and portable. Constructed from standard PCB materials with plastic keypad caps and a sealed character LCD module for continued use in typical workshop and prototyping environments. Typical applications Menu driven controllers: create device menus for configuration and control in robotics power supplies or custom appliances. Portable data displays: show sensor readings temperature levels or system status on the device without a separate display unit. Prototyping and learning: ideal for teaching embedded user interfaces where display and input hardware are needed together. Integration tips Use standard character LCD libraries for text output and simple digital input routines for keypad handling to minimize code overhead. Verify pin mapping on your host board to ensure correct alignment of power ground and data lines prior to powering up. This module is designed to simplify user interface development by combining display output keypad input and I O breakout in one compact shield compatible package.
