Product Details
4x4 Matrix Membrane Keypad 16 Key Switch Module
Add a compact 16-key matrix input panel to microcontroller projects for PIN codes, menus, and simple control UIs. This listing is for the membrane keypad only.
What it does
- Sixteen keys arranged in a 4×4 matrix for alphanumeric and function entry.
- Membrane construction keeps the panel thin for enclosure mounting.
- Matrix scanning uses fewer GPIO pins than sixteen individual switches.
- Suitable for password entry, menu navigation, and keypad-driven demos.
Compatibility and setup
- Interface with common MCU boards using a matrix keypad library or custom scan routine.
- Confirm the connector pin order against your board silk-screen or cable before wiring.
- Avoid sharp bends that can stress the membrane tail.
- Not a waterproof industrial HMI; intended for indoor prototyping and education.
Applications
- PIN and password entry prototypes
- Menu-driven Arduino and ESP projects
- Access-control learning demos
- STEM and classroom electronics labs
Package includes
- 1 × 4×4 matrix membrane keypad (16 keys)
Pin mapping depends on the cable orientation; verify continuity before coding. See the Specifications section for any listed electrical details.
