CNC Shield for Arduino Nano

The CNC Shield for Arduino Nano offers a sleek, space-saving way to create your own CNC machines. Designed specifically for the Arduino Nano, it supports 3-axis motion control and integrates smoothly with GRBL firmware. This makes it ideal for lightweight CNC projects such as mini routers, laser engravers, and plotters.

Unlike larger shields, this Nano-compatible version is perfect for compact builds. Despite its small size, it doesn’t compromise on features. You can connect A4988 or DRV8825 stepper drivers to each axis (X, Y, Z) and control your machine with precision.

In addition, the board offers ports for limit switches on all axes, a spindle enable/disable pin, and direction controls. These features allow for safer and more efficient operation. The CNC Shield fits directly onto the Arduino Nano, creating a low-profile stack that saves space and reduces wiring.

Moreover, it’s fully compatible with GRBL, the widely used open-source firmware for CNC control. You can upload G-code via a USB connection using free software like Universal Gcode Sender (UGS). For beginners and makers on a budget, this board is a great starting point.

You can pair this shield with other modules from our Electronics Components and tools from the Tools and Accessories category to build a complete machine.
