Pololu dual VNH5019 motor
driver shield for Arduino, bottom
view with board dimensions.
• Wide operating voltage range: 5.5 – 24 V
1
• 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
)
• 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
•
makes it easy to get started using this board
as a motor driver shield
• Reverse-voltage protection
• 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

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.
