This 16-button keypad provides a useful human interface component for microcontroller projects. The buttons on a keypad are arranged in rows and columns. A 4X4 keypad has 4 rows and 4 columns.
Rubber-domes beneath each button provide satisfying key travel with each button press. Each key is emblazoned with a legible white character molded into its surface.
The single-row 0.1-inch-pitch solder pads are breadboard friendly. Only eight of the ten solder pads carry signals – the solder pads on the ends of the row are purely for mechanical attachment.
