Good stepper driver
Easy to use on breadboard. Worked without the recommended 100uF cap for me, although your mileage may vary. Can get very hot to touch depending on the setting on the trim pot.

Works great
I hooked it to a NEMA-17 geared stepper and had no trouble interfacing to a raspberry pi. Very small PCB. I run the motor with a light load and board does not get hot. Not hard to solder in the two header strips if you need to. I ran wires to some holes, and put headers in the rest. Make sure you pull up the RESET pin, as it will float low and turn off the driver. Have not tried to adjust the current limiting pot, though I looked at the instructions and it seems a little complicated, but glad to have the flexibility built in.
