Note:

A single module can drive a 8×8 dot matrix common cathode

Operating Voltage: 5V

A single module can drive a 8×8 dot matrix common cathode

Operating Voltage: 5V

Dimensions: 12.8X12.8X1.3cm/

Fixing screws with 64 holes with a diameter 3mm

Module with input and output interfaces, support for cascading multiple modules

Quality:1Set

The left side of the module to the input port, the right to an output port

When the control of a single module, simply input port connected to CPU

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

Size for manual measurement, there may be a 0 to 2 cm error, belongs to the normal phenomenon.

And due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!
