TB6560 3A Stepper Motor Driver Board for 42 and 57 Stepper Motors

This TB6560 stepper motor driver board is a practical, tested solution for controlling two-phase, four-phase, four-wire, and six-wire stepper motors up to 3A. It is widely used in engraving machines, placement machines, and other equipment that requires precise motion control. The board uses a genuine Toshiba TB6560AHQ chip and includes several protection features to improve reliability during operation. While it lacks an external protection circuit, careful wiring and proper power supply selection help ensure stable performance.

Features and Construction

The driver integrates several useful features that make it suitable for both hobbyist and professional applications. From adjustable current levels to flexible subdivision settings, each component is designed to give you control over motor performance.

Current and Voltage Specifications

The driver operates on a DC supply of 10V to 35V, with a 24V switching power supply being the recommended choice. Its rated maximum output is ±3A, with a peak current of 3.5A. This makes it a good match for 42 and 57 frame stepper motors that draw up to 3A. Motors exceeding 3A should not be used with this board.

Subdivision and Speed Control

Subdivision options include full step, half step, 1/8 step, and 1/16 step, offering up to 16 subdivisions. This allows you to choose between higher torque or smoother motion depending on your application. The 6N137 high-speed optocoupler maintains signal integrity at higher speeds, reducing the chance of lost steps.

Automatic Half-Flow Function

When the motor is idle, the driver automatically reduces current to about half, which helps lower heat generation and power consumption. This is a standard feature that contributes to the longevity of both the driver and the motor.

Uses and Placement

The TB6560 driver is designed for a range of positioning and motion control tasks. Its compact size and straightforward interface make it easy to integrate into existing projects.

Engraving and Milling Machines

Many users install this driver in DIY CNC engraving machines or small milling setups. The 16-subdivision stepping provides the smooth motion needed for detailed work on materials like wood, acrylic, or soft metals.

Placement and Assembly Equipment

The driver is also suitable for pick-and-place machines where precise positioning is critical. The high-speed optocoupler helps maintain step accuracy even at higher feed rates.

General Automation Projects

For any project requiring controlled linear or rotary movement, such as 3D printers or laboratory equipment, this driver offers a reliable and affordable control solution. Its compatibility with most two-phase stepper motors expands its range of uses.

Benefits and Buying Value

This driver provides a good balance of performance and cost for users who need a simple, tested module. Its features help reduce setup time and improve system reliability.

Easy Setup with Onboard Controls

The board includes printed settings instructions, so you can adjust current levels and subdivision without needing the manual. This speeds up initial configuration and reduces the risk of incorrect wiring.

Thermal Management

A thick, dense-tooth radiator helps dissipate heat from the chip during operation. While the driver includes over-temperature shutdown as a safety backup, good airflow around the board is still recommended for continuous use.

Why Choose This Product

If you need a basic, tested stepper motor driver with genuine Toshiba components and a range of subdivision options, this board is a practical choice. It covers the most common motor sizes and voltage ranges used in hobby and light-industrial equipment. Just remember that it does not include input protection, so careful power supply selection and wiring are essential.
