S109AFTG 3A 40V Stepper Motor Driver

The S109AFTG is an easy to use professional stepper motor driver which can control a two-phase stepping motor. It is compatible with Arduino and other microcontrollers that can output a 5V digital pulse signal. S109AFTG stepper motor driver has a wide range power input, 10-47VDC power supply. And it is able to output 3A peak current, which is enough for most NEMA17 and NEMA23 stepper motors.

The stepper driver supports speed and direction control. You can set its micro step and output current with 6 DIP switch. All signal terminals adopt high-speed optocoupler isolation, enhancing its anti-high-frequency interference ability.

Note: This the S109AFTG is not recommended to control NEMA23 High Torque Stepper Motors.
