DORHEA 5Pcs TMC2208 3D Printer Stepper Motor Driver, TMC2208 V1.2 Stepper Driver Module with Heat Sink Screwdriver for 3D Printer Controller Mother Boards Reprap Ramps1.4 MKS Prusa i3 Ender-3 Pro

Package arrived in a timely manner and was exactly as described. The TMC2208 stepper motor driver is the quietest and most reliable way to drive stepper motors, IMHO, and I appreciate the inclusion of the small screwdriver to adjust the onboard potentiometer to set the limiting current (I’m not using these in a 3D printer so I don’t require the included heat sink, but most others will). Note that is is version 1.2 of the board design which means Vref is the top left hole next to the EN pin (on v2 boards it’s the middle hole in the group of three).

Absolutely the best thing I did for my Anycubic i3 mega s printer. They work great and holy moly is it quiet.

Awesome upgrade! Was running Arduino/RAMPS1.4 with A4988s. Had unrelated issues but decided to change the drivers for TMC2208s. They were a drop in replacement (I use them in legacy mode) and are just fantastic! The noise level is just about zero. The only sound I hear when I print is the retraction and a bit of motor "grind" when the printer homes at the start of a print job. Can easily forget it is on! It is really THAT much quieter!. Note on setting the driver vref, I tried it the way the doc says and was not making any progress. Instead I followed the instructions on a youtube video and it worked great. Connect your volt-meter ground to the board wired ground to the power supply. Connect your positive probe to a small metal screw driver using an alligator clip. Watch the volt-meter readout as you turn the screw driver. Easy. Get the correct sized screw driver and verify it with the board powered off. Practice getting the screw driver onto the "pot" without touching anything else. Then power all. Connect volt-meter and adjust pots. I started with about 0.95 per and had to adjust from there over a few hours of practice prints. You don't mind if the stepper motors get warm but they should not be too hot to hold on to. If you go too low you will get skips so warm motor is OK. Have fun!

I used to get the cheaper/older drivers that worked until I needed some more power. That's where these upgraded chips came in. Thank goodness they are around, and they aren't much more expensive especially in bulk. Just buy a bunch of these instead and your steppers will be silent... which I prefer to the techno buzzing symphony ambiance my projects usually have haha. Wish I bought a bunch of these chips way earlier

They work very well, I had one of them arrive damaged due to shipping, and recieved a very quick resolution from the seller! overall great purchase for the price. The one recommendation however is to look into the TMC2209 which is only a few dollars more expensive, but provides more features.
