## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Internal IC power positive and RGB positive supply; the datasheet gives an absolute supply range of 3.5-5.5 V and states the IC is 100% functional at 4.5-5.5 V. |
| 2 | DO | output | Display data cascade output that forwards the re-shaped data stream to the next LED in the chain. |
| 3 | GND | power_in | Signal ground and power ground for the IC and RGB chips. |
| 4 | DI | input | Display data input; logic input voltage is limited to -0.5 V to VDD+5.5 V, with VIH of at least 0.7VDD and VIL of at most 0.3VDD. |
