CNC Shield V3.0+ UNO R3 Board + A4988 Driver + Heatsink Kits for CNC Kit

CNC Shield Board:

    Latest Arduino CNC Shield Version 3.0
    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)
    Coolant enable
    Uses removable A4988 or DRV8825 compatible stepper  drivers
    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

Arduino UNO R3 Board:

    MCU: ATmega328

    USB interface: ATmega16U2

    Operating voltage: 5V

    Digital I/O pins: 14 (including 6  with PWM capability)

    Analog input pins: 6

    I-I/O pin output current: 40mA max

    3.3V output current: 150mA max

    Flash memory: 32 kB (0.5kB used by  bootloader - included)

    Static RAM (SRAM): 2 kB

    EEPROM: 1 kB

    Clock speed: 16MHz

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).
