  • Uses removable Pololu A4988 compatible stepper drivers. (A4988, DRV8825 and others)
  • Jumpers to set the Micro-Stepping for the stepper drivers. (Some drivers like the DRV8825 can do up to 1/32 micro-stepping )
  • Compact design.
  • Stepper Motors can be connected with 4 pin molex connectors.
