16 Relay Module PCB Design Proteus

Relay Module for controlling 230V Power supply by using 5V signal with Proteus Simulation and PCB Design and making of the PCB with the same circuit. This circuit is based upon the switching characterstics of ULN2803 Transistor. This circuit does not contain any LED or resistor. This gives direct signal to relay. The main for this is to get the PCB designed by JLCPCB at their $2 price mark. Obviously the shipping charge is more than that. This video is not sponsored by JLCPCB. I wanted to check their service and here i am, designing for that.
