(1) LC8813 LED Strip use LC8813 led chip to be the light source , it have dual signal and the capacitance is package in the led chip , so in the PCB , you can see there are no capacitance. (2) The LC8813 LED is a new LED, it is the upgrade led on the base of WS2813, they are same function, they have dual-signal transfer, two data line work at same time, so if one led broken,the other will still works.
