Using this cable is easy. First, connect the JST PH 3 - pin end to your device with a 3 - pin 'STEMMA' connector, like the HalloWing or NeoTrellis M4. Then, use the alligator clips on the other end to connect to wires or pads, such as those on the Circuit Playground or micro:bit. Remember, match the colors correctly: black to GND, white to Signal, and red to V+. When not in use, store the cable in a dry place to prevent damage. Avoid pulling the cable too hard to keep it in good condition. If you want to know more about JST PH connectors, visit the JST website.
