Description: Arduino Compatible CNC Shield V3 With 4 Pcs A4988 Stepper Motor Driver
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.
