Description :
The 4x4 Matrix Membrane Keypad is a compact and lightweight 16-key input module designed for Arduino, Raspberry Pi, AVR, PIC, and other microcontroller-based projects. It features a thin membrane design with numeric keys (0–9) and function keys, making it ideal for password systems, security locks, calculators, menu navigation, robotics, and automation projects.
The keypad uses a matrix row-column interface that reduces the number of microcontroller pins required for operation. Its adhesive backing allows easy mounting on panels, enclosures, or project boxes. With durable membrane switches and reliable tactile feedback, this keypad is perfect for DIY electronics and embedded system applications.
