| VCC | 5V |
| GND | GND |
| DIN | P2.2 |
| CS | P2.1 |
| CLK | P2.0 |
Cascading Multiple Modules
Each module features a dedicated input port (left side) and output port (right side). When using a single module, connect only the input port to your CPU. When cascading multiple modules, connect the output of the first module to the input of the second, the output of the second to the input of the third, and so on. Connect the first module's input and the last module's output to your CPU.
