Keypads
13 products
Keypads are essential input devices used in electronic projects for data entry, menu navigation, password input, and more. Available in matrix, membrane, and numeric configurations, these components must be chosen based on project requirements. They are widely used in Arduino, Raspberry Pi, and other microcontroller-based platforms.
Matrix keypads, typically 3x4, 4x4, or 4x5, allow multiple keys to be read with a limited number of GPIO pins by using row-column scanning. This approach is efficient in coding but may require software debouncing. Membrane keypads, on the other hand, are thin, flexible, and water-resistant, making them suitable for industrial control panels, home automation, and portable devices. Some models come with customizable graphic overlays.
When selecting a keypad, consider the number of keys and layout, interface (digital pin, I2C, analog), mechanical durability, operating temperature, and dimensions. For high-usage projects, mechanical feedback models are recommended; for outdoor use, IP-rated membrane keypads are the better choice.
