Connect the anode (positive electrode) of each bead of the unit module to supply current uniformly from RGB, and supplycurrent from PCB to bead.
The anode (positive terminal) of the bead of each line of the unit module is connected, and R, G and B are powered respectively. The volta-ge and current are correctly distributed to the red, green and blue beads, and the current reaches the negative IC terminal through the lamp bead.
