S109AFTG 1 Axis 4A Stepper Motor Driver Controller 9-40V Micro-Step (TB6600 Alternative)
Price in Sri Lanka

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, 10-40VDC 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.

Specifications
