Using these cables is super easy. For the blue Flotilla ropes, simply connect one micro B end to your Flotilla module and the other to the Dock. You can choose the right length according to your project requirements. For the red Dock cable, plug the USB A end into your computer and the micro B end into the Flotilla Dock. When using, make sure the connectors are well - inserted to avoid disconnection. As for maintenance, keep the cables away from sharp objects to prevent damage. Also, don't pull the cables too hard. If you're not using them for a long time, store them in a dry and cool place.
