Pololu Dual MC33926 Motor Driver Shield for ArduinoThis shield makes it easy to control two brushed DC motors with your Arduino or Arduino compatible board. Its dual MC33926 motor drivers operate from 5 to 28 V and can deliver a continuous 3 A per motor. These great drivers also offer current sense feedback and accept ultrasonic PWM frequencies for quieter operation. The Arduino pin mappings can all be customized if the defaults are not convenient, and the motor driver control lines are broken out

This shield makes it easy to control two brushed DC motors with your Arduino or Arduino-compatible board. Its dual MC33926 motor drivers operate from 5 to 28 V and can deliver a continuous 3 A per motor. These great drivers also offer current-sense feedback and accept ultrasonic PWM frequencies for quieter operation. The Arduino pin mappings can all be customized if the defaults are not convenient, and the motor driver control lines are broken out along the left side of the shield for general-purpose use without an Arduino.

This motor driver shield and its corresponding Arduino library make it easy to control two bidirectional, brushed DC motors with an Arduino or Arduino clone. The board features a pair of Freescale MC33926 motor drivers, which operate from 5 to 28 V and can deliver a continuous 3 A per channel, and includes current sense circuitry, protection resistors, a FET for reverse battery protection, and logic gates to reduce the required number of I/O pins. It ships fully populated with its SMD components, including the two MC33926 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).

This versatile motor driver is intended for a wide range of users, from beginners who just want a plug-and-play motor control solution for their Arduinos (and are okay with a little soldering) to more advanced users who want a dual MC33926 carrier that requires fewer I/O pins to control. The Arduino pin mappings can all be customized if the defaults are not convenient, and the simplified MC33926 control lines are broken out along the left side of the board, providing a convenient interface point for other microcontroller boards (see the right connection diagram below). This versatility, along with an option to power the Arduino directly from the shield, sets this board apart from similar competing motor shields.

Features
  • Wide operating voltage range: 5 – 28 V 1
  • Output current: 3 A continuous (5 A peak 2) per motor
  • Inputs compatible with both 5 V and 3.3 V systems
  • PWM operation up to 20 kHz, which is ultrasonic and allows for quieter motor operation
  • Current sense voltage output proportional to motor current (approx. 525 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 on motor supply 3
  • Robust drivers:
    • Transient operation up to 40 V
    • Over-current limiting via internal PWM
    • Over-temperature shutdown and hysteresis
    • Under-voltage shutdown
    • Output short-to-ground and short-to-Vcc protection

A good shoe from a trusted brand
Size: 13 Wide, Color: Medium Natural Nubuck, Size: 13 Wide, Color: Medium Natural Nubuck
I'm mostly happy with these so far. They're generally well made, they look great, and I know they'll last a long time. They're real leather, which is always greatly appreciated in this synthetic era. They are pretty dang supportive and comfortable overall. They're lightweight and the price is right. But there are a few negatives, mainly on the comfort front. The right shoe fits perfectly, but the left one isn't quite right. It feels like the top of the heel is stitched a little too tight, such that it digs into the back of my heel when I walk. Now, this isn't uncommon for me with new shoes, but I do kind of expect better from Rockport. The other issue is that the shoes feel a little bit slippery on low pile carpets and tile. Now I'm sure both of those issues are temporary, and will resolve as the shoes break in. Still, they're noticeable. What can I say? They're Rockports. You know they're going to be solid shoes. I almost love these shoes, and really, I'm sure in a few months, when they're fully broken in, I will love them unreservedly. But not quite yet.

Sharp looking dress shoes
Size: 14 Wide, Color: Medium Natural Nubuck
These shoes look great in person and have a clean, classic style that works well for the office, church, or more formal occasions. The natural nubuck gives them a nice appearance without being overly flashy, and they look more expensive than they actually are. The fit was good in the wide size, and they were comfortable right out of the box. The overall quality seems very good, with solid construction and materials that feel like they should hold up well over time. For the price, they're a good value and a nice option if you're looking for a sharp looking pair of dress shoes.

All day comfort!
Size: 12, Color: Grey Nubuck
I was looking for a pair of dress shoes that I could spend a lot of time in and be comfortable. I am happy to report that I’ve found them! I’ve always heard a lot about the Rockport brand, but never wanted to cough up the money that I do for say, Hoka athletic shoes. I can now see what folks do. Very comfortable right from the unboxing. My feet are so happy. The shoes themselves look great, and feature a really strong build quality. The price is a little on the steep side, but I’m learning you get what you pay for in most cases. Definitely a great product that I won’t hesitate to purchase again when needed.
