Features: The TMC2130 has two phase stepper motors. drive current 1.2A, peakcurrent 2A, 12V/24VDC, 256 subdivision. With a standard SPIinterface, you can use SPI mode on your SKR 2/SKR Pro board directly by setting jumper cap Excellent heat dissipation and low heat,it has large-area cooling position to lower the temperature. TMC2130 stepper motor driver reduces motor noise to silence at low velocities to ensures noiseless operation, maximum efficiency and best motortorque. The noise of the motor is below 10dB, which is much lower than that of the traditional current controller.
