This motor driver board ships with all of the surface-mount parts populated. However, soldering is required for assembly of the included through-hole parts. The following through-hole parts are included:
A 0.1″ shorting block (for optionally supplying shield power to Arduino) is also included.
You can solder the terminal blocks to the six large through-holes to make your motor and motor power connections, or you can break off a 12×1 section of the 0.1″ header strip and solder it into the smaller through-holes that border these larger holes. Note, however, that each header pin pair is only rated for a combined 6 A, so for higher-power applications, the terminal blocks should be used or thick wires should be soldered directly to the board.
When not using this board as an Arduino shield, you can solder the 0.1″ headers to the logic connections along the left side of the board to enable use with custom cables or solderless breadboards, or you can solder wires directly to the board for more compact installations. Note that motor and motor power connections should not be made through a breadboard.
The mounting hole is intended for use with #4 screws (not included).
An Arduino is not included.
