TRINAMIC has released their new stepper motor, the TMC2100, which is already being embraced by the hobbyist and 3D printing community due to its list of enhancements, such as integrated MOSFETS and no required intervention by a host CPU. It also features noise reduction, which is an attractive benefit for those using the motor in close proximity. The stepper motor comes in a package with its sister product, the TMC2130, which offers added versatility and full diagnostics.
