User Manual

Pololu dual VNH5019 motor driver shield for
Arduino with included hardware.
1
While the overvoltage protection typically activates at 27 V, it can trigger at voltages
as low as 24 V, so we do not recommend using this motor driver with 24 V batteries,
which significantly exceed 24 V when fully charged. If the shield is configured to power
an Arduino or Arduino clone, the supply voltage must conform to that Arduino’s input
voltage requirements.
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
[https://www.pololu.com/product/2440] (for shield power and motor outputs)
• 40-pin 0.1″ straight breakaway male header [https://www.pololu.com/product/965] (may ship in
several pieces, such as two 20-pin strips)
A 0.1″ shorting block [https://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 [https://www.pololu.com/
category/70/crimp-connector-housings] or solderless breadboards [https://www.pololu.com/category/28/
