TMC2209 V1.2 are the latest generation of silent stepper motor drivers from Trinamic. Using their patented StealtChop technology, they can deliver exceptionally quiet stepper motor performance with noise levels below 10 dB.
For a perfect balance of quiet operation and maximum performance, the TMC2209 drivers are able to automatically switch between StealthChop and SpreadCycle modes. This means an overall better 3D printing experience with less noise, more torque, and fewer missed steps.
TMC2209 drivers do support Legacy and Standalone modes, but the UART configuration is highly recommended. It will take full advantage of serial communications, offering full diagnostics and control over the stepper motors via the firmware. This means motor current and microsteps can be set arbitrarily on the fly, and combine the real and interpolated microsteps to achieve maximum torque.
