Microcontroller External Keypad Module


4×4 Matrix 16-Key Microswitch Keypad Module

This compact external keypad module features 16 tactile microswitches arranged in a 4-row × 4-column matrix, designed

 for seamless integration with microcontrollers (e.g., Arduino, STM32, Raspberry Pi).

Key Features

  • Efficient I/O Utilization: Uses only 8 pins (4 rows + 4 columns) to detect 16 keys via row-column scanning logic, saving microcontroller resources.

  • Tactile Feedback: Momentary microswitches deliver clear, responsive input for reliable user interaction.

  • Easy Integration: Pre-soldered 2.54mm pin headers (90° rotated) enable quick connection to breadboards or PCBs; labeled pins simplify wiring.

  • Durable Design: Green PCB construction with stable mounting options (M3 holes) ensures longevity in DIY or embedded projects.

Applications

Ideal for password entry systems, DIY electronics (e.g., digital locks, robotics controls), home automation panels, and educational projects (teaching matrix scanning principles). It supports common development platforms with readily available code libraries (e.g., Arduino Keypad library) for fast setup.
