The TMC2130 v3.0 is a two-phase stepper driver with a standard SPI interface and a step/dir interface. Because the driver is equipped with interpolation functionality, it is possible to have 1/256 microsteps on the output with a 1/16 microstep driver. This makes the TMC2130 v3.0 an incredibly quiet driver, so that no heavy CPU is required. The stepper driver also offers power control, for energy savings of up to 75%.
