• A single module can drive a 8x8 dot matrix common cathode
• Operating Voltage: 5V
• A single module can drive a 8x8 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 5VGND GNDDIN P2.2CS P2.1CLK 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!
