Using these cables is super easy. First, for the blue Flotilla ropes, just connect one micro B end to your Flotilla module and the other to the Dock. Depending on your project, pick the right length - 10cm, 25cm, or 50cm. For the red Dock cable, plug the USB A end into your computer and the micro B end into the Flotilla Dock. When handling the cables, be gentle with the connectors to avoid damage. To keep them in good condition, store them in a dry place when not in use. If you notice any signs of wear or fraying, it's best to replace the cable.
