Description

CNC shield V4 is compatible with Nano board. Used as driver expansion board for CNC engraving machine and 3D printer. There are 3 channel slots for stepper motor driver.Each channel of stepper motor only needs 2 IO ports, which means 6 IO ports is sufficient to manage 3 stepper motors. This shield can make quick work for managing stepper motors in your project.

Specifications
1. 3 axis stepper motor driver
2. Compatible with micro-drive laser engraving machine, three-axis CNC engraving machine,.
3. 2A can be controlled within the two-phase four-wire stepper motor.
4. Released the digital IO interface, easy to connect to other modules, such as ENDSTOP.
5. Released the I2C interface, you can connect to the LCD I2C or other I2C module.
6. Power DC 5V interface, 7.5-12V voltage input.
7. compatible with GRBL.
8. Work with aduino nano.
