Pololu Dual VNH5019 - Manual (Page 4)

Pololu dual VNH5019 motor driver shield for
Arduino with included hardware.
1.b. Included Hardware
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:
• one extended/stackable 1×10 female header (for
Arduino shields)
• two extended/stackable 1×8 female headers (for
Arduino shields)
• two extended/stackable 1×6 female headers (for
Arduino shields)
• three 2-pin, 5mm terminal blocks
[http://www.pololu.com/product/2440] (for shield power and
motor outputs)
• 40-pin 0.1″ straight breakaway male header [http://www.pololu.com/product/965] (may ship in several pieces,
such as two 20-pin strips)
A 0.1″ shorting block [http://www.pololu.com/product/968] (for optionally supplying shield power to Arduino) is also
included.
You can use the terminal blocks to make your motor and motor power connections, or you can break off an 12×1
section of the 0.1″ header strip and solder it into the smaller through-holes that border the six large motor and motor
power pads. Note, however, that the terminal blocks are only rated for 16 A, and each header pin pair is only rated for
a combined 6 A, so for higher-power applications, 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 [http://www.pololu.com/category/70/crimp-connector-housings] or
solderless breadboards [http://www.pololu.com/category/28/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 motor driver includes three 47 uF electrolytic power capacitors, and there is room to add additional capacitors
(e.g. to compensate for long power wires or increase stability of the power supply). Additional power capacitors are
usually not necessary, and no additional capacitors are included with this motor driver.
The two mounting holes are intended for use with #4 screws [http://www.pololu.com/category/101/nuts-and-screws] (not
included). They have a horizontal separation of 0.30″ and a vertical separation of 1.70″.
An Arduino [http://www.pololu.com/product/2191] is not included.
