Description TB 6600 stepper motor controller TB 6600 stepper motor controller 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. It has a wide range power input 9~42VDC power supply. It is able to output 4A peak current, which is enough for most stepper motors. Features Support 8 kinds of current control Support 7 kinds of micro steps adjustable The interface has 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 Comments When “EN” is Low, the motor is in a free state (Off-line mode). In this mode, you can adjust the motor shaft position manually; when “EN” is High (Vacant), the motor will be in an automatic control mode. “Direction” is the motor direction signal pin, “PULSE” is the motor pulse signal pin. Once it gets a pulse, it moves a step.
