The CNC Shield V3.0 allows you to build a engraving machine, 3D printer, mini CNC and other similar devices using your Arduino. It is designed as a shield and can plug on top of an Arduino requiring no external connections and wiring. There are 4 slots on the board for plugging in stepper motor drive module which can drive 1 stepper motor each. Controlling each step stepper motor requires only two IO pins on the Arduino. Just insert this Arduino CNC Shield V3.0 onto an Arduino UNO, and install the GRBL firmware, you can then quickly build a DIY CNC engraving machine. 

Features:-

• The extension board can be used for Small CNC routers, Carving Machine, 3D Printers, DIY Laser Cutters, and almost any project where you need to control a stepper motors with high precision
• This shield allows you to control upto 4 stepper motors
• Controller each stepper motor requires 2 IO Pins only, which saves a lot of IO Pins for other purposes
• Arduino compatible
• Latest Arduino CNC Shield Version 3.10
• GRBL 0.9 compatible. (Open source firmware that runs on an Arduino UNO that turns G-code commands into stepper signals)
• Supports 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)
• Supports Coolant enable
• Supports removable A4988 compatible stepper drivers. (A4988, DRV8825 and others) (Not Included)
• 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.)
• Uses removable A4988 or DRV8825 compatible stepping driver.

This is ULN2003 Driver Module Stepper Motor Driver Board for driving and controlling stepper motors.

ULN2003 Stepper Motor Driver Board uses the ULN2003 DARLINGTON ARRAYS to drive the 4-phase 5-wire stepper motor (5v-12v).

It’s easy to use Arduino or another development platform to drive the stepper motor by this diver board.

The 5 Line 4 Phase can be driven by ordinary ULN2003 chip can also be connected in phase 2 development board used for supporting the use of a direct plug and easy to use stepper motor used in the development board. A, B, C, D four-phase LED indicates the status of the stepper motor work.
