a4988 stepper motor driver for nema 17 stepper motor in Pakistan

  • its supply voltage is 8 to 12V DC.
  • it has 1A current without a heatsink.
  • it gives 1.5 A current with the heat sink.
  • 3 to 5.5V is logical input.



A4988 driver stepper motor driver is a complete micro-stepping motor driver with a built-in converter. this stepper motor driver is easy to operate. this motor driver operates from 8V and 35V. this motor driver can deliver up yo approximately 1A phase without a heat seak. this motor driver is rated for 2A per coil with sufficient additional cooling. A4988 driver stepper motor driver contains a fixed off-time current regulator. this regulator can be in slow or mixed decay mode. this converter is the key to the easy implementations of the A4988. this motor driver does not have any phase sequence tables, the high- frequency control interface programming, etc. this driver is very suitable for the complex microprocessors which are not available or overload. In the operation of stepping, chopping control in the A4988 will automatically select the current decay mode
