Description: Arduino Compatible CNC Shield V3 With 4 Pcs A4988 Stepper Motor Driver
4Pcs A4988 Stepper Motor Driver With V3 CNC Shield Arduino Compatible For DC Motor Driver Engraving Machine 3D Printer Expansion Board
This expansion board, as drive expansion board, can be used for engraving machines and 3D printers. It totally has four slots and can drive 4 A4988 stepper motors, and each stepper motor only needs two IO ports. That is, 6 IO ports can be well managed three stepper motors. A4988 is a complete micro-stepping motor driver with built-in translator for easy operation.
- Latest CNC shield V3 expansion board: each stepper motor needs only 2 IO ports.
- A4988 driver module: suitable for driving 8V ~ 35V stepper motor, five different step modes.
- 4-Axis support(X, Y, Z, A-Can duplicate X,Y,Z or do a full 4th axis with custom firmware using pins D12 and D13).
- Jumpers to set the Micro-Stepping for the stepper drivers.
- A4988 driver expansion board can be used for engraving machines and 3D printers.
