Using this cable is easy. First, connect the JST PH 3-pin end of the cable to the appropriate port. Then, attach the sensors or LEDs to the female header sockets at the other end. The color-coded wires will help you make the right connections. When handling the cable, be gentle to avoid bending or breaking the wires. Store it in a dry and cool place to keep it in good condition. If you have any issues, refer to the JST website for more information.
