Pinout

Pin Name Type Function
1 VDD power_in Power supply pin; the absolute maximum rating for VDD is +3.7 V to +5.3 V.
2 DOUT output Control data signal output that sends the reshaped data stream to the next cascaded pixel.
3 VSS power_in Ground pin used for both data and power grounding, with VSS defined as 0 V.
4 DIN input Control data signal input that receives serial data from the controller; the first pixel latches its 24-bit data from this pin.
