TB6600 is an easy-to-use professional stepper motor driver, which could able to drive 57, 42-type two-phase, four-phase, hybrid stepper motor. It is compatible with microcontrollers that can output a 5V digital pulse signal. TB6600 arduino stepper motor driver has a wide range power input, 9~40VDC power supply. And it is able to output 4A peak current, which is enough for the most of stepper motors. 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. Features Support 8 kinds of current control Support 7 kinds of micro steps adjustable The interface adopts high-speed optocoupler isolation Automatic semi-flow to reduce heat Large area heat sink Anti-high-frequency interference ability Input anti-reverse protection Overheat, over current and short circuit protection Specification Input Current: 0~5A Output Current: 0.5~4.0A Control Signal: 3.3~24V Power (MAX): 160W Micro Step: 1, 2/A, 2/B, 4, 8, 16, 32 Temperature: -10?45?
