Descrição

Kit Matriz LED 16x16 Keyestudio

Informação do fabricante:

Keyestudio LED dot matrix display module connects four 8 * 8 dot matrix. Line selection is chosen by 4-16 decoder which consists of two 74HC138, and as for the strobe line, LED anode will be connected. Column output consists of two 74HC595 cascades, which can convert serial data into parallel data through the SPI signal.

When a column’s output signal is a high level, LED cathode on the column is also a high level, so that the LED located in intersection of the selected line and column doesn’t light up.

On the contrary, when the column’s output signal is a low level, the LED cathode on the column is also a low level, so that the LED located in intersection of the selected line and column will light up.

After passing a row, 74HC595 outputs the line data. A total of 16 lines cycle in turn with dynamic scanning, which can make 16 * 16 dot matrix show the required text or graphics.
