TB6600 module is stepper motor driver which provides 4.5A maximum output current.
TB6600 has a output sort-circuit protection, Low-Pressure shut-off, Overheating parking and over-current protection.
Output current is infinitely adjustable to meet various applications.
Automatic half current function. And a semi-automatic flow switch, easy to use
The use of high-speed optical coupling 6N137 ensure high-speed without losing step
Used to increase the heat sink, good heat dissipation
