4x4 Matrix Keyboard with Female Pin Connector

Description

Whether your project is space constrained or you just want a cool look and a high tech keypad, the 4 x 4 membrane keypad is the ideal choice for your project.

The board is self adhesive, and you can attach it to almost any surface by peeling the sticker from its back and sticking into the desired location.

The button states can be detected by reading the combination of four rows and four columns provided by the matrix keypad. Underneath each key, there is an ultra thin push button connected with one end to a row, and the other end to a column, as shown below:
