BIGTREETECH TMC2209 V1.2 Stepper Motor Driver 2.8A Peak Driver 3D Printer Parts for SKR V1.4 Turbo, SKR V1.4, SKR Pro V1.2, SKR V1.3 Motherboard (2 PCS)

If you're going to be controlling motors (NEMA in my case), these drivers work great.

Works great and I like the larger than "usual" heatsinks. Very quiet operation.

Works great

Switching to TMC2209 drivers from the older DRV8825s significantly reduced the noise in my projects. These drivers operate so quietly, it's a noticeable improvement for anyone aiming to minimize sound. I installed the TMC2209s on a DRV8825 shield/expansion board that I found on Amazon, and they fit well. There are a couple of extra pins that don't connect to anything, but they're not needed for the driver to work effectively. One thing to keep in mind is the microstepping capability of the TMC2209s, which goes down to 1/8th. This might result in slower movement compared to some other drivers, but the reduction in noise and smooth operation more than compensates for the slight dip in speed.

I spent three hours trying to move a stepper motor with well written code, a microcontroller I knew worked, and a power supply I knew worked with this board. I probed it with a multimeter and tested it with my power supply. I finally found that two of the pins (the ground and external voltage source pin) were switched, so it was not properly allowing a constant voltage to be set for the driver. In the end, I did figure it out, but it was mislabeled.
