The CNC shield stepper motor driver V4 for 3D printers needs to operate with the Nano board. It can be used as an expansion driver board for engraving machines and 3D printers. It has a total of 3 channel slots for A4988 driver modules (not included) to drive 3 channels of stepper motors. Each stepper motor channel requires only 2 IO ports, which means that 6 IO ports are enough to manage 3 stepper motors. This board facilitates the management of stepper motors in your project.

Specifications:

• 3-axis stepper motor driver
• Compatible with micro-driven laser engraving machine, three-axis CNC engraving machine
• Can control up to 2A in 4-wire two-phase stepper motors
• Has a digital IO interface, easy connection with other modules like ENDSTOP
• Has an I2C interface for connection with I2C LCD or other I2C modules
• DC5V interface, 7.5-12V input voltage
• Compatible with GRBL
• Works with Arduino Nano
