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:-

• It has a nice standard 0.1″x0.1″ prototying grid with big pads
• Comes with Stacking headers and plain header, choose whichever you want when soldering together
• A IC pattern for adding DIP ICs up to 20 pins
• Power rails down the middle and sides
• A reset button and an extra general use button
• 2 3mm general use LEDs, red and green, as well as 2 matching resistors
• A pass-thru ICSP stacking header so you can stack any kind of shield on top, and/or use an AVR programmer
• A surface-mount chip area for up to 14 SOIC size parts
• Compatible with tiny breadboards
• Every pin is brought out!
• Gold plated pads
• 2 x 0.1uF capacitors on either side for extra power stability
