BIGTREETECH TMC2209 V1.3 UART Stepper Motor Driver Module VS TMC2100 TMC2130 for Octopus V1.1/Octopus Pro/SKR V1.4 Turbo/SKR 3/Manta M8P/M4P/M5P 3D Printer Controller Board 1Pc

A breeze to work with... I purchased a different stepper motor controller, and well......let's say after HOURS of diagnosing why my motor was just buzzing... even breadboarded a 1Hz astable multivibrator circuit to watch the drive pattern, and verifying the motor was wired correctly. All "appeared" to be right, but yet, the motor just buzzed at me. Decided to give this driver a try -- worked right "out of the box" -- connected to my triggering circuit (not the astable multivibrator) and watched the motor spin like expected. Don't go cheap or off-brand -- save yourself the headache... BUY THIS DRIVER!Now, I can refocus my efforts on the real task, not figuring out what the driver is doing.

Bamm, just like that brought my Artillery S2 back to printing. I have to say after trying several other replacements, this one is dead silent like the original driver. Thank you!Edit:Awwww for some reason the step motor on my printer now runs backward. Boo. I think it's still a five star for someone else. I don't want to learn how to edit my firmware for this.

I am not an expert with these types of motor controllers. I first bought a Synthetos shield but was noisy.When I went to build a second device, they were out of stock so I ended up buying a CNC shield off Amazon with some other motor drivers.. It was a disaster, never worked right, was noisy when it worked, was missing steps, caught fire once, ended up shorting out and blowing up my laptop.Then I bought a set of these. I had to remove the two extra pins for diagnostics, because they were in the way of the CNC shield’s own pins. This was easily achieved by heating up the solder joints, and then pulling out the pins.With that being said, I plugged it directly into the CNC shield, and it was instantly working correctly, with no missed steps, and very quietly.. much quieter than the other motor controllers and much quieter than the G shield.I highly recommend these motor drivers

I'd been working on a stepper arduino controller, I tried several drivers.- first was the L289N - wayyyyyy too much current, motor and controller too hot to touch, 60 Watts!- second was the DRV8825 - much better, but there was still quite a bit of noise and the motor rumbled around on the table- third was TMC2209 - This hit the sweet spot, motor is inaudible and heat is very much under control

Works great!

The media could not be loaded. Overall seems to be a good product. Took a star off because the header pin soldering job wasn’t great, stray solder on some of the posts that I had to remove with solder wick before I could connect them to anything. Documentation is a little rough. Used in a raspberry pi zero 2w project. I found a good library, TMC-2209-Raspberry-Pi 0.5.7, which also had good instructions for how to wire things up. To get the UART to work bidirectionally, connect RX on TMC to RX on pi directly. Then short the Pi RX to the Pi Tx via a 10k resistor. Would not work with MS1 and MS2 floating, have to tie them both to ground to use address 0. Works great with nema17s.

I really like these BTT 2209's. They are a bit less expensive on Amazon than most 3D printing stores but are the exact same product you would buy.

These little guys work good. Prices seemed to have jumped a little.
