The 2×12 female header included with the reflectance sensor array should be soldered to the front expansion area of the Zumo shield so that it is centered in the expansion area and flush with the Zumo chassis (rows 2 and 3). While it is fine to solder all 24 pins to the shield, only the 12 pins required by the reflectance sensor array need to be soldered (see the Array pinout section below for more information on which pins are required). | The 2×12 female header included with the reflectance sensor array should be soldered to the front expansion area of the Zumo shield so that it is centered in the expansion area and flush with the Zumo chassis (rows 2 and 3).
