MAX7219 Dot Matrix Module For Arduino Microcontroller 4 In One

Description: 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 modulesWiring 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 CPU3. 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 Package list: 1x SainSmart MAX7219 Dot Matrix Module 4-in-one 1x 20cm DuPont line 5P Documents: Manuals
