  • This driver expansion board is suitable for 3D printers and engraving machines
  • It can drive up to four A4988 stepper motors and each motor only needing two IO ports
  • Note: When inserting the A4988 module, you must be careful not to insert opposite wires. The stepper motor wiring should be as follows: 2A and 2B is a group (red, green), 1A and 1B is a group (blue, yellow). If want to change the direction you need to swap the wires in the same group, for example switch 2A with 2B
