TB6560 CNC Router Single Axis 3A Stepper Motor Driver

The TB6560 Stepper Motor Driver Board is a robust, single‑axis driver module designed for precise control of bipolar stepper motors in CNC routers, 3D printers, automation systems and robotics applications. Built around the original TB6560AHQ driver IC from Toshiba, this board supports bipolar two‑phase motors with currents up to ±3 A (peak up to ±3.5 A) and a supply range from approximately 10 V to 35 V DC.

Features:
Utilizes Toshiba TB6560AHQ chip for reliable bipolar stepper motor control
Rated maximum output current of ±3A, with peak capacity of 3.5A
Supports multiple microstepping modes: Full, 1/2, 1/8, and 1/16 step resolution
Integrated 6N137 high-speed opto-couplers provide input signal isolation from motor noise
