Youmile 6 pcs TMC2208 V1.2 3D Printer Stepper Motor Driver Module Adjustable with Heat Sink screwdriver for 3D Printer Controller Mother Boards Reprap MKS Prusa i3 Ender-3 Pro

I am legitimately shocked by how quiet these drivers are.I am running 2 NEMA11 motors for a project and the A4988 & DRV8825 drivers i had laying around were LOUD.I swapped the drivers over, adjusting only the VREF and they work flawlessly, and silently.I haven't even tried the UART functionality yet.Why 3D printer manufacturers aren't using these for all modern printers baffles me.

These are great value. The quality seems high for the price. Also silent as the TMC2209 should be.Will be buying these again when needed.

The boards that arrived did not have the DIAG pin installed on the board and no additional pins were supplied. The listing shows pins on the board in the pictures - they are not there.Unusable for sensorless homing.Refund was not requested as I can use them for a different project, but they are not as listed!
