BIGTREETECH TMC2209 V1.3 UART Stepper Motor Driver Ultra-Silent Stepsticks with Heatsink Mute for Octopus V1.1/Octopus pro/SKR V1.4 Turbo/SKR 3/Manta M4P/M5P/M8P 3D Printer Motherboard 5PCS

Got these to replace 4988 drivers so I could drive 24 volt motors. They are a direct plug in replacement on the Arduino cnc shield with two caveats. First there are two pins sticking down between the two rows which are not necessary. I cut them flush. Second, be very careful to identify orientation. They are different than the 4988. Produce absolutely silent motor drive. Excellent

Working great on my CNC plasma.

I installed these on my Anycubic mega s and low noise level and print quality is insane

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

these work much better than the A4988 drivers for about A4988 drivers I was using. The poteniometer adjustments are accurate (don't need much of a turn). They stay cool.
