TMC260 Stepper Motor Driver Shield For Arduino
Share this Product
INTRODUCTION
This is a stepper motor driver introduced by DFRobot for those projects require powerful stepper motors, such as a pair of automatic curtains, an XY Plotter. This shield allows Arduino drive stepper motors (up to 2A per motor coil, 40V max). This stepper motor drive shied adoptes a TMC260 chip which is
