Cut the Header SectionsCut the breakaway header strip into sections to fit the holes on the edge of the shield. You will need 2 sections of 6-pins and 2 sections of 8 pins.
You can use wire-cutters as shown or pliers to snap them apart between pins.
Insert the Headers into an ArduinoTo align the header strips for soldering, insert them (long pins down) into the headers of an Arduino.
Note that for R3 and later Arduinos, there will be an extra 2 unused pins on the end closest the USB and DC power jacks.
