This motor driver shield and its corresponding Arduino library make it easy to control two bidirectional, high-power, brushed DC motors with an Arduino or Arduino clone. The board features a pair of robust VNH5019 motor drivers from ST, which operate from 5.5 to 24 V and can deliver a continuous 12 A (30 A peak) per channel, and incorporates most of the components of the typical application diagram on page 14 of the VNH5019 datasheet (629k pdf), including pull-up and protection resistors and FETs for reverse battery protection. It ships fully populated with its SMD components, including the two VNH5019 ICs, as shown in the picture to the right; stackable Arduino headers and terminal blocks for connecting motors and motor power are included but are not soldered in (see the Included Hardware section below).
- 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
- 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 makes it easy to get started using this board as a motor driver shield
- Detailed user’s guide
- 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 kicks in 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.
