Adafruit Motor/Stepper/Servo Shield for Arduino Kit (Motors not included)NOTE: Motors Servos shown in photos are not included. We have upgraded the shield kit to make the bestest, easiest way to drive DC and Stepper motors. This shield will make quick work of your next robotics project! We kept the ability to drive up to 4 DC motors or 2 stepper motors, but added many improvements: Instead of a L293D darlington driver, we now have the TB6612 MOSFET drivers with 1. 2A per channel current capability (you can draw up to 3A

- We have upgraded the shield kit to make the bestest, easiest way to drive DC and Stepper motors. This shield will make quick work of your next robotics project! We kept the ability to drive up to 4 DC motors or 2 stepper motors, but added many improvements:
- Instead of a L293D darlington driver, we now have the TB6612 MOSFET drivers with 1.2A per channel current capability (you can draw up to 3A peak for approx 20ms at a time). It also has much lower voltage drops across the motor so you get more torque out of your batteries, and there are built-in flyback diodes as well.
- Instead of using a latch and the Arduino's PWM pins, we have a fully-dedicated PWM driver chip onboard. This chip handles all the motor and speed controls over I2C. Only two data pins (SDA & SCL in addition to the power pins GND & 5V) are required to drive the multiple motors, and since it's I2C you can also connect any other I2C devices or shields to the same pins. This also makes it drop-in compatible with any Arduino, such as the Uno, Due, Leonardo and Mega R3.
- Completely stackable design: 5 address-select pins means up to 32 stackable shields: that's 64 steppers or 128 DC motors! What on earth could you do with that many steppers? I have no idea but if you come up with something send us a photo because that would be a pretty glorious project.
- Lots of other little improvements such as a polarity protection FET on the power pins and a bit of prototyping area. And the shield is assembled and tested so all you have to do is solder on straight or stacking headers and the terminal blocks.
Specifications:
- 2 connections for 5V 'hobby' servos connected to the Arduino's high-resolution dedicated timer - no jitter!
- 4 H-Bridges: TB6612 chipset provides 1.2A per bridge (3A for brief 20ms peaks) with thermal shutdown protection, internal kickback protection diodes. Can run motors on 4.5VDC to 13.5VDC.
- Up to 4 bi-directional DC motors with individual 8-bit speed selection (so, about 0.5% resolution)
- Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil, interleaved or micro-stepping.
- Motors automatically disabled on power-up
- Big terminal block connectors to easily hook up wires (18-26AWG) and power
- Arduino reset button brought up top
- Polarity protected 2-pin terminal block and jumper to connect external power, for separate logic/motor supplies
- Tested compatible with Arduino UNO, Leonardo, ADK/Mega R3, Due, Diecimila & Duemilanove. Works with Mega/ADK R2 and earlier with 2 wire jumpers.
- Download the easy-to-use Arduino software library, check out the examples on the Adafruit website and you're ready to go!
Comes with an assembled & tested shield, terminal block, plain header, jumper. Some soldering is required to assemble the headers on. Stacking headers not included, but we sell them in the shop so if you want to stack shields, please pick them up at the same time. Arduino and motors are not included but we have lots of motors in the shop and all our hobby servos, DC motors, and stepper motors work great.
Note: The terminal block included with your product may be blue or black.
Technical Details:
Dimensions, assembled: 70mm x 55mm x 10mm 2.7"x2.1"x0.4"
This board/chip uses I2C 7-bit addresses between 0x60-0x80, selectable with jumpers.

Durable, interesting, but not my dog's favorite.
Color: Purple, Size: Large (Pack of 1)
This is a pretty cool treat dispensing toy; the rubber it's made from is very thick and durable, and the irregular shape of it makes it more interesting for the dog.
The opening of each compartment has little strips inside that makes the toy dispense treats pretty randomly. You can also snip them so they're shorter, to dispense treats easier. I snipped all of them in my toy, because my dog was having a hard time getting treats out, and I adjusted them several times to where now it's almost too easy to get the treats out. I just couldn't find a happy medium, and of course once you've cut them, you can't uncut them.
The only real down side to this toy is that it collects dog fur and can get pretty gross pretty fast. Most of my dog's other toys stay relatively clean when she's using them, but between the material and the pattern and whatnot on the outside, this toy is just a gunk magnet. Fur collects in the little dips between "barnacles" and clings to the slots on the outside of the toy. My dog doesn't really mind, obviously, but I think it's a little gross. ;D My dog for whatever reason favors most of her other toys over this one; even when this is the only toy that still has treats left in it, she'll often ignore it. It's a very high quality toy, though.

Durable and Fun Diversion!
Color: Purple, Size: Large (Pack of 1)
At first I was a bit concerned as the toy is made of a fairly pliable rubber so I worried that my vizsla, who destroys most of his toys rather quickly, would destroy this one within hours. Luckily, I was able to quickly teach him that it's much more fun to carry and kick around, then to gnaw.
So far it's been over a month that I've actually left this on the floor, and it shows very little signs of damage. Some treats have made a perpetual home in the large and medium sides of the toy, and it keeps him interested from time to time, as he'll just randomly pick it up and start kicking it around, or bring it to me in hopes of a game of fetch or a treat reload.
One thing that definitely helped him fall in love with it was that I immediately (after washing) placed a variety of sizes of his favorite treats in the different globes. Some (kibble-sized) treats fell out easily and taught him that this was indeed a rewarding toy to play with, others took a little kicking and dropping, and some remain until they start to break apart from enough bouncing and licking, which keeps his attention.
We have the large (for a 40-lb dog) and it suits him well as he can get his mouth around even the largest of the globes to carry it, while it has about a zero percent change of becoming a choking hazard, unless a piece breaks off, which seems unlikely so far.
One does have to be somewhat careful playing fetch in the house, as it bounces somewhat unpredictably and has a bit of heft to it.
Very pleasantly surprised to find that the rubber actually smells good, somewhat like bubble gum, as opposed to some other rubber toys that reek of chemicals.
Overall, very happy with the durability, safety, and fun of this one, and wouldn't hesitate to replace it with the exact item if it is ever lost or damaged.

3.5 Stars -- Sturdy but Limited
Color: Purple, Size: Large (Pack of 1)
I got the Barnacle toy in size Large for my ~45 lb mutt. She enjoys food toys, and I wanted to find one sturdy enough that I felt safe leaving her with when I left for work since she tends to destroy her toys quickly.
First thing -- there's no way any dog is going to be able to destroy this. The "rubber" is super thick and a good balance of flexible and sturdy, so she can't do her favorite "pick at a weak edge and slowly disembowel it" trick. I've had it for a couple months now and it looks brand new.
However, it isn't great for feeding her kibble. She eats 1 cup at morning and at night, and none of the compartments fits that comfortably. I don't really feel like dividing her food into 3 portions every day to split it between either. The bigger problem is the hole size, or rather the ratio of kibble-to-hole size. The holes are very big with rubber "fingers" inside to slow the food spill. I've still found that it tends to dump a fistful of kibble all at once, or not let anything go for a long time. This may have to do with my dog's "technique", as described below.
Another problem is that since this has three separate chambers, this toy is not hollow and is surprisingly heavy. While my dog has no problems throwing a kong around (and I mean THROWING a kong around), the weight and asymmetrical shape makes it difficult to throw or roll, which is my dog's preferred way to use a food toy. This toy works best when a dog slaps it with her paws or picks it up and drops it, which may be why my dog gets frustrated with getting her food from it.
What this toy is really great for, for us, is high value treats. If I am leaving at an unusual time and anticipate that she's going to fuss, I can put "the good stuff" in this toy and then she doesn't mind the struggle at all! The different size chambers make this especially nice if I'm breaking up odd sized or home made treats and want her to stay busy for a while. Since it's so sturdy, she can chew on it all she wants, but she has to do the work to get the treats.
All in all-- this toy isn't great for my dog's daily feedings, but it's great for high value treats and a change of pace.

Actually a challenge for my genius dog!
Color: Purple, Size: Large (Pack of 1)
I am pretty sure my dog owns every puzzle toy and treat-dispensing dog toy that exists, and he's able to figure most of them out in less than 5 minutes. Many last no more than 60 seconds before he's solved them.
The Barncle, however, is actually a challenge for him!
The Barnacle has three "compartments, " none of which are connected. All three have a rubber "mouth" that helps keep treats inside. The rubber "mouth parts" are very effective and make it quite challenging to get treats out once they've been placed inside. You can trim the rubber "mouth parts" to make it easier to let treats out, but I'm not doing that. I'm glad that it's not challenge!
The Barnacle keeps my dog occupied for at least 30 minutes, which is a LONG time for my dog who usually has a "What next?" attitude towards toys.
Th only "bad" thing about the Barnacle is that it's so hard to get treats out of, even for humans. Therefore, it could attract vermin if you're not careful to clean it out.
