This stepper driver does the job in a compact form factor. Great for upgrading 3D printer stepper drivers, it's capable of handling substantial current and the heatsink makes sure you won't overheat.

I do a lot of hobby electronics with Arduino and MSP430 microcontrollers and needed another driver after one got installed backward and fried. This works great and can drive a full 1.5A if you use the supplied heatsink. Make sure the heatsink is installed in a way that it doesn't contact the adjacent pins and short something out.

I am happy with this item.I bought this to control a small stepper motor with an Arduino Nano and it works great.The construction looks great and the unit was well packaged. If I had any criticism it would be that no documentation was included but a quick web search had me going in no time. The board is tiny and it's amazing it can provide as my power as it can.I recommend this item to anyone needing to control a small stepper motor in a tight space.

I have not yet had the opportunity to hook up the driver. I am still waiting for a stepper motor to arrive. I plan to use this to learn coding to run the motor. The coding will be used to run a more powerful motor for a project I am designing. If this does not work as I think it should, I might have to change my rating but for now it appears to merit 5 stars.

When I ordered this board, I really didn’t know anything about it (e.g., that the chip+form factor are pretty common), only that I’ve hard a project that would need a stepper motor controller. Minus one star because it doesn’t come with any docs—even a tiny piece of paper with a URL to docs would have been nice. Lucky for me, because it is so common, there is a lot of info available online[Disclosure: I received this product for “free”—in quotes because the IRS considers the item’s retail value as taxable income for federal income tax purposes.

Works well with my DIY mini-router table. I'm not pulling much current with my small plastic table, so can't vouch for how close to the 2A drive current they claim it operates - but at much lower levels I can confirm it's been stable and works as I expected! Partial step operation (e.g. 1/4 step, 1/8 step, etc.), and works with the Arduino sketches - just flip it over and connect the labels like this to your arduino:To connect the A4988 to an Arduino:- VDD and GND (next to VDD) to Arduino's 5V and Ground- DIRECTION and STEP pins to Arduino digital output pins (e.g., 2 and 3)- stepper motor coils to 2B, 2A, 1A, and 1B pins- motor power supply to VMOT and GND (8-35V)The MS1, MS2, and MS3 pins control the step resolution. Set them like this:- Full step: low, low, low- 1/2 step: high, low, low- 1/4 step: low, high, low- 1/8 step: high, high, low- 1/16 step: high, high, highThat should get you up and running with the example sketches. Fun, inexpensive, functional little circuit.
