Arduino CNC SHIELD V.3 + 4Drive A4988

CNC Shield v3 Engraving Machine / 3D Printer / + 4pcs A4988 Driver Expansion Boar

4 x A4988 Stepper Motor Driver with Heat Sink + CNC Shield Expansion Board for Arduino V3 Engraver New


CNC Shield Board:

Latest CNC Shield Version 3.0 for Arduino.
GRBL 0.9 compatible. (Open source firmware that runs on an UNO for Arduino 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)
2 x End stops for each axis (6 in total)
Coolant enable
Uses removable A4988 or DRV8825 compatible stepper drivers
Jumpers to set the Micro-Stepping for the stepper drivers. (Some drivers like the DRV8825 can do up to 1/32 micro-stepping )
Compact design.
Stepper Motors can be connected with 4 pin molex connectors or soldered in place.
Runs on 12-36V DC. (At the moment only the DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board.)
Please note that this is an unassembled kit and Basic soldering skills are needed.

A4988 Stepper Motor Driver:

A4988 Stepper Motor Driver Board is a breakout board for Allegro’s A4988 DMOS Micro stepping Driver with Translator and Overcurrent Protection; please read the A4988 datasheet carefully before using this product.
Low RDS (On) Output
Automatic current decay mode detection / selection
Mix with slow current decay modes
Synchronous rectification for low power dissipation
Internal UVLO
Crossover-current protection
3.3 and 5 V compatible logic supply
Thermal shutdown circuitry
Ground fault protection
Load short-circuit protection
Five selectable step modes: full, 1/2, 1/4, 1/8 and 1/16
Warning: Connecting or disconnecting a stepper motor while the driver is powered can destroy the driver. (More generally, rewiring anything while it is powered is asking for trouble).

Package Includes:

1 x CNC Shield Board
4 x A4988 Stepper Motor Driver
4 x Heat Sink
