Keypad 3*4

12 tactile membrane keys arranged in 4×4 matrix

Adhesive back for permanently mounting keypad

3″ long 8-pin cable terminates in standard 2.54mm (0.1″) female header.

These membrane keypads work well for adding key input for a project.

The construction makes them durable and weatherproof.

The row pins are on the left as you are looking at the front of the keypad and they have a dark strip near the connector to help identify them.

The connector is a standard 2.54mm (0.1″) pitch 1×8 female header.

The matrix is resistive which means that when no button is pushed, none of the pins are electrically connected. When a button is pressed, the corresponding Row and Col pins have a resistance of approximately 60-90 ohms between them
