Robotico 4x4 Matrix 16-Key Keyboard Module

The 4x4 Matrix 16-Key Keyboard Module is an efficient and cost-effective input solution that allows users to easily input data through a compact 4x4 matrix keypad. With 16 tactile buttons, this module is perfect for various applications, including security systems, industrial automation, consumer electronics, and robotics.

Key Features:

Universal Matrix Keypad: Features a 4x4 grid layout with 16 buttons, enabling 16 unique combinations for versatile input.
Easy Integration: Equipped with an 8-pin header on the upper part of the board for straightforward connections to Arduino or other microcontrollers.
Standard Pin Header Pitch: 2.54mm pin header pitch, ideal for prototyping and breadboard setups.
Durable Design: Rated for up to 1 million presses, ensuring long-lasting performance.
Compact Size: Measures just 43mm x 39mm, making it suitable for a wide range of projects.

Specifications:

Insulation Resistance: 100M at 100V for reliable operation.
Maximum Current and Voltage: Handles up to 100mA and 35V, ensuring safety in various applications.
Contact Bouncing Time: Approximately 5ms, providing reliable button presses without false triggers.
How It Works: The 4x4 matrix keypad operates by utilising a grid of 16 buttons, with unique connections between rows and columns. Each button press creates a connection between the corresponding row and column pins. The module connects to the Arduino with four pins designated for row connections and four for column connections. The Arduino scans each row to detect button presses and identifies which button has been activated based on the corresponding column.

Applications:

Security Systems: Use the keypad for access control, requiring a code for entry.
Industrial Automation: Enter data or control machinery with ease.
Consumer Electronics: Ideal for remote controls, gaming devices, and more.
Educational Projects: Perfect for teaching programming, electronics, and microcontroller interfacing.
Robotics: Utilise the keypad for controlling robots and automated systems.

Upgrade your projects with this versatile 4x4 Matrix 16-Key Keyboard Module and enjoy its ease of use, compact design, and robust functionality.
