Shield CNC + A4988 x3 + Arduino + cable usb

Descripción

Shield CNC v3.0

• Version:3.0
• Color:Red
• Size(L*W*H):68 x 53 x 18 mm
• Voltage:DC 12~36 V (At the moment only the DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board.)

Features:

• Uses removable A4988 or DRV8825 compatible stepper drivers.
• The extension board can be used for carving machine, 3 d printer driver expansion board
• GRBL 0.8 compatible. (Open source firmware that runs on an Arduino UNO that turns G-code commands into stepper signals)
• PWM Spindle and direction pins,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)
• Compact design. Stepper Motors can be connected with 4 pin molex connectors or soldered in place.
• Please note that this is an unassembled kit and Basic soldering skills are needed.

A4988 Stepper Motor Driver
