1. A single module can drive a 8×8 dot matrix common cathode
2. Operating voltage: 5V
3. dimensions: length 12.8 cm X 12.8 cm wide and 1.3 cm high X
4. fixing screws with 64 holes with a diameter 3mm
5. module with input and output interfaces, support for cascading multiple modules

Wiring instructions:

1. The left side of the module to the input port, the right to an output port.
2. When the control of a single module, simply input port connected to CPU
3. When a plurality of cascaded modules, input and output termination CPU, an input terminal of the second output end of the first module a module, the first two modules of the input terminal of the three termination modules, and so on. ..
51 microcontrollers, for example:
VCC → 5V
GND → GND
DIN → P2.2
CS → P2.1
CLK → P2.0

LED matrix displays can be used to display almost anything. Most modern LED sign boards uses various types of matrix boards with controllers. In this tutorial we are going to interface a single color 8×8 LED matrix with Arduino and display a few characters in it.

8×8 matrix consists of 64 dots or pixels. There is a LED for each pixel and these LEDs are connected to total of 16 pins.
