Nano CNC Shield Expansion Board

Description

This CNC Shield expansion board can be used as a drive expansion board for engraving machines and needs to be used with an Arduino Nano. There are 3 slots on the board for stepper motor driver modules, so it can drive 3 stepper motors. Each stepper motor needs only two IO ports that is to say, 6 IO ports can quite well manage three stepper motors, which is very convenient to use.

The CNC Shield breaks out some of the GPIO of the Arduino Nano, making it convenient to connect other modules such as limit switches. The CNC Shield V4.0 also has an I2C interface, so you can connect an LCD screen that has an I2C interface.

The input voltage of the CNC Shield V4.0 is DC 7.5V–12V. Do not exceed 12V.

Features:

• 3-axis stepper motor driver
• Compatible with micro-drive laser engraving machines and three-axis CNC engraving machines
• Can control 2A two-phase four-wire stepper motors
• Breaks out the digital IO interface, easy to connect to other modules such as ENDSTOP
• Breaks out the I2C interface, so you can connect an I2C LCD or other I2C module
• DC 5V power interface, 7.5V–12V voltage input
• GRBL compatible
• Works with Arduino Nano
