Grove - 4-pin Male Jumper to Grove 4-pin Conversion Cable (5 PCs per Pack). Grove is a convenient plug-and-play system with a specialized interface, but that doesn't mean it couldn't be used in an open ecosystem like breadboard. With these specially designed conversion cables, you can easily integrate the comprehensive Grove system with breadboard or other microcontrollers that don't have compatible Grove-Base Shield for now. If you are tinkering around Raspberry Pi, Cubieboard, or Beagle Bone and be fond of the advantage of Grove, this conversion cable is recommended.
