TMC series driver with a mute function and capable of driving up to 4.33 A current. This enables quiet operation while delivering strong motor torque when needed. Low heat generation and easy cooling, delivering ultra quiet performance for continuous or longlasting use. Microstep control via a DIP switch, with a maximum of 64 microsteps for smoother motion and precise positioning. Safe optically coupled isolation signal to provide reliable, noise control and protection between the controller and the driver. Use scenario: CNC machines and milling/rabric or engraving setups where quiet operation and reliable current drive improve productivity and reduce vibration. Use scenario: 3D printers or lasercutting systems requiring precise microstepping, low heat, and quiet operation for cleaner workflow and better print quality. Use scenario: Robotic automation or pickandplace systems that need configurable current, fast response, and robust signal isolation for dependable performance in noisy environments.
