Matrix Membrane Switch Keypad – 4×4 (16 Key) & 4×3 (12 Key) for Arduino

Take your Arduino, Raspberry Pi, or microcontroller project to the next level with this versatile Matrix Membrane Switch Keypad. Available in both 4×4 (16-key) and 4×3 (12-key) configurations, this ultra-thin, flexible keypad is the go-to input solution for DIY electronics, robotics, home automation, access control panels, and embedded systems.

The membrane-style construction makes it lightweight, durable, and easy to integrate into enclosures or project housings. Its standard matrix pin-out is compatible with a wide range of microcontrollers right out of the box, and it requires no soldering — just plug in the ribbon connector and start coding.

Key Features

  • Two Configurations Available: 4×4 matrix (16 keys: 0–9, A–D, *, #) and 4×3 matrix (12 keys: 0–9, *, #)
  • Plug-and-Play Compatibility: Works directly with Arduino Uno, Mega, Nano, Raspberry Pi, STM32, and other popular microcontrollers
  • Thin, Flexible Membrane Design: Low-profile construction ideal for mounting in tight spaces or custom enclosures
  • Standard Ribbon Cable Connector: Easy to connect — no soldering required
  • Matrix Scanning Architecture: Efficiently reads multiple keys using fewer I/O pins (4 rows + 4 columns for 4×4; 4 rows + 3 columns for 4×3)
  • Durable & Long-Lasting: Rated for thousands of keystrokes with a reliable tactile response
  • Customizable: Available in customized configurations to suit specific project requirements
  • Made in China

Frequently Asked Questions

Q: Is this membrane keypad compatible with Arduino and Raspberry Pi?

A: Yes! The matrix membrane switch keypad is fully compatible with Arduino (Uno, Mega, Nano, etc.), Raspberry Pi, STM32, and virtually any microcontroller that supports digital I/O. Simply use the standard Keypad library for Arduino and you're ready to go in minutes.

Q: What is the difference between the 4×4 (16-key) and 4×3 (12-key) versions?

A: The 4×4 (16-key) keypad includes numeric keys 0–9 plus A, B, C, D, *, and # — ideal for projects needing alphabetic input or more functions. The 4×3 (12-key) keypad includes 0–9, *, and # — perfect for numeric entry and phone-style input applications. Both use a matrix scanning layout to minimize the number of I/O pins needed.

Q: Does this keypad require any soldering?

A: No soldering is required. The keypad comes with a pre-attached ribbon cable connector that plugs directly into a breadboard or jumper-wire header, making setup quick and beginner-friendly.

Q: Can I get a custom configuration of this membrane keypad?

A: Yes, this keypad is available in customized configurations. If you need a different layout, labeling, or size for your project, custom options are available — please reach out for more details.
