Product Description
Let your robotic dreams come true with the new DC+Stepper Motor HAT from Adafruit. This Raspberry Pi add-on is perfect for any motion project as it can drive up to 4 DC or 2 Stepper motors with full PWM speed control.
Since the Raspberry Pi does not have a lot of PWM pins, we use a fully-dedicated PWM driver chip onboard to both control motor direction and speed. This chip handles all the motor and speed controls over I2C. Only two pins (SDA & SCL) are required to drive the multiple motors, and since it's I2C you can also connect any other I2C devices or HATs to the same pins.
In fact, you can even stack multiple Motor HATs, up to 32 of them, for controlling up to 64 stepper motors or 128 DC motors (or a mix of the two) - just remember to purchase and solder in a stacking header instead of the one we include.
Motors are controlled by TB6612 MOSFET drivers with 1.2A per channel current capability (you can draw up to 3A peak for approx 20ms at a time), a big improvement over L293D drivers and there are built-in flyback diodes as well.
We even had a little space so we added a polarity protection FET on the power pins and a bit of prototyping area. And the HAT is assembled and tested here at Adafruit so all you have to do is solder on the included 2x20 plain header and the terminal blocks.
Install the easy-to-use Python library, check out the examples and you're ready to go!
Comes with an assembled & tested HAT, terminal blocks, and 2x20 plain header. Some soldering is required to assemble the headers on
Customer reviews
Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
Learn more how customers reviews work on AmazonCustomers say
Customers like the performance, ease of use, and quality of the computer component. For example, they mention it works great, the software library is easy to follow, and the board is easy assemble. Customers are also impresseded with the learning section of the Adafruit website, saying it's fun to experiment with. That said, some complain about the durability, saying the product is very fragile and can't handle any serious load.

Works great. Fits on a Raspberry PI 3 and 4 with no issues. I have used it to drive separate motors with no issues.
I have not driven stepper motors with it however.
Setup was fairly easy, be forwarned that you'll need a soldering iron and some solder. The boards inputs\outputs were left to the user to solder themself. You'll be making 50 solder joints on fairly small pins, so if you don't have a soldering iron I'd recommend getting one with a fine tip.
The board is unpowered by the Raspberry Pi as would be expected; the specifications claim that the board can support 1.2A continous current with tolerance for 3A spikes. I haven't ran the board near it's limit yet as my motors are rated for 300mA each (so a grand total of 600mA) but from my observations thus far it appears that the board is fairly efficient. It's not getting hot from any of it's components, even the voltage regulator. This board will sit over the entire face of the Raspberry Pi 2, but has a notch cut out for the camera port which was a nice addition, my only gripe so far about the board is that it takes up all 40 of the GPIO slots and doesn't offer an extenders. There are holes made available for unused ports but you need to buy the headers yourself, or just get an expansion board.
All in all though it's a good well built product. All solid state parts (no relays). I dropped it on a cement floor from standing height and the board works just fine.
Other considerations:
*input voltage: 5-12V (Curious to see if it will operate at lower than recommended voltages as I want to power my Pi and this board with a cell phone battery bank)
*Nice bright green power LED on the board if you have any gripes with green LEDs
*The screw terminals would be best installed 2 pieces at a time; the kit includes 2x 2-port screw terminals and 2x 3-port screw terminals. The terminals appear to have a mate scheme to them to allow them to sit nicely with each other, so I'd recommend inserting those together when you go to solder
*The screw terminals require a pretty small phillips screw driver, consider getting on if you don't have one laying about.
*Minimalistic packaging. The board came in a bubble wrap envelope inside of a anti-static bag. No box or instructions included.
*I had to install the smbus library for Python to get this board to work; I followed the instructions found at http://skpang.co.uk/blog/archives/575 without a hitch. You'll need to use the command sudo i2cdetect -y 1 (on the Pi 2) in order to find which address(es) you can use in your python code. The Adafruit examples used 0x61 where as I can use 0x60/0x70.
