Features:
- V3 Engraver 3D Printer CNC Shield Expansion Board A4988 Driver for Arduino
- This expansion board can be used for engraving machines & 3D printers
- 4 stepper motor connection. Each connection can control one A4988 motor
- That means you can connect 4 stepper motors into this board
- Each road stepper motors only need two IO ports
- In other words, six IO ports can be well managed
- Connection Instruction
- When inserting the A4988 module, must be careful not to insert opposite
