CNC Shield stepper motor driver module

The Grbl CNC Shield allows you to build a CNC machine in the fastest and easiest way, you only need to add an Arduino one, a few A4988 or DRV8825 drivers and a compatible Shield CNC V3 Driver A4988 - DRV8825, is mainly used in CNC engraving machines and in 3D printing by expanding to the Arduino Uno.

Compatible with GRBL software in version 0.8c. Open source firmware that runs on an Arduino turning the G-code commands into electrical signals to move the stepper motors.

The Arduino compatible CNC expansion shield translates the digital commands of our computer into orders by steps, this is done through 4 driver A4988 or you can also use 4 DVR8825 driver to control stepper motors, each of which you need two IO ports to function.

Specifications:

• DC operating voltage: 12V
• 4 support axes: X, and Z, A (A axis A can double the x, y, z or default axes, make a complete fourth axis with custom firmware using D12 and D13 pins)
• Running ends: 2 for each axis (6 total)
• 4-pin molex to connect PAP motors
• Dimensions: 70 mm x 55 mm x 18 mm
