The TB6600 Stepper Motor Driver is an easy-to-use professional stepper motor driver for a two-phase stepping motor. It is compatible with Arduino and other microcontrollers that can output a 5V digital pulse signal. TB6600 stepper motor driver has a wide range power input 9~42VDC power supply. It is able to output 4A peak current.

This stepper driver supports speed and direction control. You can set its micro step and output current with 6 DIP switch. There are 7 kinds of micro steps (1, 2 / A, 2 / B, 4, 8, 16, 32) and 8 kinds of current controls (0.5A, 1A, 1.5A, 2A, 2.5A, 2.8A, 3.0A, 3.5A) in all.  All signal terminals adopt high-speed optocoupler isolation, enhancing its anti-high-frequency interference ability.
