The TMC2208 v3.0 is a single-axis stepper motor drive chip, equipped with interpolation functionality. This makes it 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 70%.
