This board is widely used for driver expansion board of  engraving machin. There are total 4 ways slots for stepper motor driver modules (Model A4988 or Drv8825 – It sold separately at our store ), and it can drive 4 ways stepper motors each up to 2A. Each way stepper motor has two I/O ports and it means 6 I/O ports can manage 3 stepper motors. It is very convenient to operate.
