This connector is a double-row, 14-pin, extended male header strip. The extra-long pins have a length of 22.85 mm, which is 11.2 mm longer than typical 0.1" straight male header pins. The standard 0.1" spacing allows use with perforated prototyping PCBs and female headers.
This connector was specifically designed for routing electrical connections from the 3pi robot base to an expansion board. It is provided as part of the 3pi expansion kits, including the PCB-less hardware-only kit.
A two-pin version of this extended header is also available, as is a shorter version.
