## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Power supply pin; the datasheet specifies VDD of 4.5 to 5.5V for the IC. |
| 2 | DOUT | output | Data output pin that sends the control data signal on to the next cascaded pixel after reshaping. |
| 3 | VSS | power_in | Ground pin for power and signal (listed as GND in the function table). |
| 4 | DIN | input | Data input pin that receives the control data signal; input high threshold is 0.7*VDD and low threshold is 0.3*VDD. |
