3.b. Assembly for Use as an Arduino Shield
1. Stackable Arduino headers: Before you can use this board as an Arduino shield, you need to solder
four of the five included Arduino header strips to the set of holes highlighted in red in the picture above.
The headers should be oriented so that the female sockets rest on the top side of the shield and face up while
the male pins protrude down through the board, and the solder connections should be made on the underside
of the shield. The newest Arduino boards, including the Uno R3 and the Leonardo, use one 10×1 header,
two 8×1 headers, and one 6×1 header, as shown in the left picture below; older Arduino boards use two 8×1
headers and two 6×1 headers, as shown in the right picture below (the two pairs of pins highlighted in darker
red should not be populated if you are using this board with an older Arduino that does not support these
additional pins). Please make sure you solder the appropriate headers for your particular Arduino!
2. Motor and power connections: The six large holes/twelve small holes on the right side of the board,
highlighted in yellow in the above diagram, are the motor outputs and power inputs. You can optionally
solder the included 5mm-pitch terminal blocks to the six large holes to enable temporary motor and motor
