Pinout

Pin Name Type Function
1 VDD power_in Logic supply pin, with the absolute maximum logic supply voltage stated as 3.5 to 5.5 V.
2 DO output Data output that retransmits the received control data to the next cascaded pixel, with a typical DO source current (IDOH) of 15 mA and sink current (IDOL) of 30 mA.
3 GND power_in Common ground for both signal and power, as stated in the pin function table.
4 DIN input Control data input, with high-level input VIH of 0.7VDD to VDD, low-level input VIL of 0 to 0.3VDD, and logic input voltage rated -0.5 to 5.5 V.
