This seems like a poor pin-assignment choice given that the Arduino Mega 2560 has four 16-bit timers that could have been assigned to those pins instead, including Timer 1, but maybe there are some other constraints I’m not aware of that led to that decision. Unfortunately, for some reason, these same pins on the Arduino Mega 2560 correspond to the hardware PWM outputs of Timer 2, which is an 8-bit timer. This allows for an ultrasonic PWM frequency. On the Uno, these pins correspond to the hardware PWM outputs of Timer 1, the ATmega328’s only 16-bit timer. The VNH5019 motor shield connects to digital pins 9 and 10 on the Arduino. Please don't hesitate to ask if you have any questions, and we welcome your feedback! The motor shield library is available now on github, and a detailed user's guide will be available in the next few days.
Terminal blocks, 0.1" male headers, and stackable Arduino headers are included.įor more information, please see the dual VNH5019 motor driver shield product page.Arduino analog inputs aren't wasted on the driver's digital fault outputs.Driver PWM pins are connected by default to Timer 1 PWM outputs rather than Timer 0 like on the Monster Moto, so ultrasonic (20 kHz) PMW frequencies can be used for quieter operation (the shield library configures the timer this way).The power inputs and motor outputs are on the opposite side of the board from the Arduino's USB connector and power jack, and they don't short to the grounded USB connector like on the Monster Moto.Motor driver pins are also broken out along the left side of the shield for general-purpose use.Ability to reconfigure the Arduino pin mappings if the defaults aren't convenient or to disconnect pins you don't want to use (e.g.Ability to power the Arduino from the motor shield through a removable jumper.Works with 3 V systems and 5 V systems (logic high threshold is 2.1 V on the VNH5019 compared to 3.25 V on the VNH2SP30).Operation up to 24 V (overvoltage protection on the VNH2SP30 can kick in at 16 V).The VNH5019, just released by ST, is essentially a more versatile version of the VNH2SP30, so the dual VNH5019 motor shield's performance is similar to Sparkfun's Monster Moto shield, except with several key improvements:
Our Arduino library simplifies interfacing with the shield by providing methods for setting the motor speed and direction, reading the motor current, and checking for motor faults. The shield operates from 5.5 to 24 V and can deliver a continuous 12 A (30 A peak) per motor. svg).We at Pololu are happy to present the Dual VNH5019 Motor Driver Shield for Arduino, an easy way to control two high-power, brushed DC motors with an Arduino or Arduino clone. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 This repository contains all part definitions that are shipped with the fritzing fritzing installation contains a clone of this repository and is continuously updated through github, so take great care when making changes.
