Using this cable is easy. Just connect it between the two devices you want to link, like a GPIO Expander bonnet or RGB LED Matrices. Make sure to align the white - striped Pin #1 correctly when plugging it in. When handling the cable, be gentle as it's flexible and can be damaged if bent too sharply. For storage, keep it in a cool, dry place to prevent any moisture damage. If it gets dirty, you can use a soft, dry cloth to clean it. That's all you need to know to get the most out of your cable!
