Commonly referred to as a shunt or shorting block, this jumper is used to connect two pins together ona SIP header. This is done to enable or disable a device, or to set an address or a channel on a device. The 0.1" spacing makes this jumper compatible with the SIP headers and Proto boards we currently carry, allowing you to select between VIN and VDD on servo headers.
