Driver TB6600 upgraded version

 TB6600 Upgraded Version Stepper Motor Driver – High-Power, Reliable Motor Driver for CNC, 3D Printers & Automation Projects

 Overview:

The upgraded TB6600 is a powerful stepper motor driver designed to control NEMA 17, 23, or 34 stepper motors in CNC machines, 3D printers, laser engravers, and robotics. It offers higher current support, microstepping, and robust protection features compared to older drivers.

 Key Specifications:

• Operating Voltage: 9V – 42V DC
• Output Current: Up to 4A (peak)
• Microstepping: 1, 2A, 2B, 4, 8, 16, 32 (switch selectable)
• Control Signal Voltage: 3.3V – 5V compatible (works with Arduino, Raspberry Pi, etc.)
• Supports Step & Direction control
• Overheat, overcurrent, and short-circuit protection

 What’s Upgraded?

• Improved heat dissipation
• More stable current output
• Higher microstepping precision
• Often labeled as “TB6600 single-axis driver” or “4A CNC stepper driver”

 Typical Wiring:

• ENA+ / ENA-: Enable (optional)

• DIR+ / DIR-: Direction control

• PUL+ / PUL-: Step pulse control

• A+ / A-, B+ / B-: Connect to stepper motor coils

• Power Input: 12V–36V DC

  Notes:

• Ensure correct current limit via DIP switches to match your stepper motor

• Use an external power supply (not USB)

• Always double-check coil wiring of your stepper motor (A+/A−, B+/B−)
