User Manual

Pololu dual VNH5019 motor

driver shield, assembled and

connected to an Arduino Uno R3.

Pololu dual VNH5019 motor

driver shield for Arduino, bottom

view with board dimensions.

• Wide operating voltage range: 5.5 – 24 V

• High output current: up to 12 A continuous (30 maximum)

per motor

• Motor outputs can be combined to deliver up to 24 A

continuous (60 A maximum) to a single motor (see

Section 7)

• Inputs compatible with both 5V and 3.3V systems (logic

high threshold is 2.1 V)

• PWM operation up to 20 kHz, which is ultrasonic and

allows for quieter motor operation

• Current sense voltage output proportional to motor current

(approx. 140 mV/A)

• Motor indicator LEDs show what the outputs are doing

even when no motor is connected

• Can be used with an Arduino or Arduino clone (through

shield headers) or other microcontroller boards (through

0.1″ header along the left side)

• When used as a shield, the motor power supply can

optionally be used to power the Arduino base as well

• Arduino pin mappings can be customized if the default

mappings are not convenient

• Arduino library [http://github.com/pololu/dual-vnh5019-motor-shield] makes it easy to get started

using this board as a motor driver shield

• Reverse-voltage protection to -16 V

• Robust drivers:

◦ Can survive input voltages up to 41 V

◦ Undervoltage and overvoltage shutdown

◦ High-side and low-side thermal shutdown

◦ Short-to-ground and short-to-Vcc protection
