What is a stepper motor? Stepper motor is a brushless DC electric motor that divides a full rotation into a number of equal steps The motor\’s position can then be commanded to move and hold at one of these steps. How to control a stepper motor?The fast way to control a stepper motor is just using a stepper motor driver (controller). And TB6600 arduino is just what you need. TB6600 arduino is an easy-to-use professional stepper motor driver, which could control a two-phase stepping motor. It is compatible with Arduino and other microcontrollers that can output a 5V digital pulse signal. TB6600 arduino stepper motor driver has a wide range power input, 9~42VDC power supply. And it is able to output 4A peak current, which is enough for the most of Stepper motor . The 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 control (0.5A, 1A, 1.5A, 2A, 2.5A, 2.8A, 3.0A, 3.5A) in all. And all signal terminals adopt high-speed optocoupler isolation, enhancing its anti-high-frequency interference ability. As a professional device, it is able to drive 57, 42-type two-phase, four-phase, hybrid stepper motor. Note: this is a newest upgrade version of TB6600 stepper motor driver.
