4 * 4 Matrix Button STEAM Education Kit Maker Education Robot Artificial Intelligence Education Hardware

$14.00

4*4 matrix keys, also known as column keyboard, use 4 I/O lines as row lines and 4 I/O lines as column lines to form a keyboard. A button is set at each intersection of the row line and the column line, so that there are 4*4 keyboard keys. This row-column keyboard structure can effectively improve the I/O port utilization of the microcontroller system.
