Using the Grove to Grove connector is easy. Simply connect the two female Grove ports to the appropriate devices for RGB LED strip extensions. When using the Grove to Pin converter, connect the single pins to your device that doesn't have a Grove port. For the Grove to SERVO converter, connect it between the M5Core and the servo motor to use the Grove port on the M5Core. Make sure all connections are secure to avoid signal loss. When not in use, store the connectors in a dry and clean place to prevent damage. Avoid bending or pulling the connectors too hard as it may break the pins.
