The 4x4 Membrane Keypad is a simple and flexible input device commonly used in embedded systems for user input. It consists of 16 buttons arranged in a 4-row by 4-column matrix, allowing for the input of numerical digits, characters, or control commands. Its slim design and adhesive backing make it easy to integrate into a wide range of projects, including DIY electronics, microcontroller-based systems, and robotics.

Key Features:

• Matrix Layout: 4 rows and 4 columns, offering 16 keys for input
• Compact and Thin: The membrane design makes it lightweight and easy to attach to surfaces
• Flexible Cable: Features a flexible ribbon cable with 8 pins for easy interfacing with microcontrollers like Arduino
• Durable: Built with robust membrane material that withstands repeated pressing
• Easy to Interface: Can be connected to digital I/O pins on a microcontroller for detecting key presses
• Adhesive Backing: Simplifies installation by allowing direct mounting on surfaces

Applications:

Ideal for embedded systems, calculators, password entry systems, home automation, and any project requiring a compact user input .
