Using these Flotilla cables is easy. First, if you want to connect Flotilla modules to the Dock, just plug one end of the blue micro B to micro B cable into the module and the other end into the Dock. To connect the Dock to your computer, use the red USB A to micro B cable. When choosing a cable length, think about your project requirements. For smaller setups, the 10cm cable might be enough, while larger projects could need the 50cm one. Keep in mind that these cables are designed for specific current needs, so don't use them for other high - current devices. To maintain these cables, avoid bending them sharply or pulling on them too hard. Store them in a dry place when not in use to prevent damage.
