Using these Flotilla cables is a breeze. First, for the blue micro B to micro B cables, you can connect your Flotilla modules to the Dock according to your project needs. Just pick the right length - 10cm, 25cm, or 50cm. Then, use the red USB A to micro B Dock cable to connect the Dock to your computer. When handling the cables, be gentle to avoid bending or breaking them. Store them in a cool, dry place when not in use. If they get dirty, you can use a soft, dry cloth to wipe them clean. That's all you need to know to keep your Flotilla cables working great!
