Matrix Keyboard is a kind of keyboard whose layout is like a matrix and it’s used as a peripheral equipment of MCU. The structure of matrix keyboard is more complex than that of other common keyboards, and the condition is similar to that of the recognition. The column line is connected with the anode of the power supply through resistors and let the I/O port of MCU connected with the row line work as an output terminal. The I/O port connected with the column line will be the input.

Because during the circuit design, there is much more need of external input. It will consume much IO source if we control a button separately, we have the matrix keyboard. The most common types are 4*4 and 8*8. Among them, the type 4*4 is even more common than 8*8.
