TB6560 3A Single Axis Stepper Motor Driver Module 10-35V 1-16 Microstep

The TB6560 3A single axis stepper motor driver module is a compact, high-performance controller board built around the Toshiba TB6560AHQ PWM chopper-type driver chip. Designed for CNC routers, 3D printers, laser engravers, and robotic automation systems, the board operates from a 10V to 35V DC supply, with a 24V switching power supply recommended for stable performance. The rated output current is ±3A with a peak capability of 3.5A, making it suitable for two-phase, four-phase, four-wire, and six-wire stepper motors rated up to 3A, including common 42 and 57 series frames. Microstep resolution is configurable across full step, half step, 1/8 step, and 1/16 step modes, allowing smooth motion and reduced resonance at low speeds. The input stage uses a 6N137 high-speed optocoupler for signal isolation, preserving step accuracy at high pulse rates. Built-in low-voltage shutdown, overheat shutdown, and overcurrent protection circuits safeguard the driver and motor under demanding conditions. An automatic semi-flow (half-current) function reduces holding current when the motor is idle, lowering heat generation. The board features a thick-toothed aluminum heat sink for efficient thermal dissipation, measures 50mm × 75mm × 35mm, and includes printed setup instructions on the PCB for configuration without a separate manual.
