Arduino UNO CNC Shield v3

This board is widely used for driver expansion board of engraving machin. There are total 4 ways slots for stepper motor driver modules (Model A4988 - It sold separately at our store ), and it can drive 4 ways stepper motors each up to 2A. Each way stepper motor has two I/O ports and it means 6 I/O ports can manage 3 stepper motors. It is very convenient to operate.

A4988 Driver CNC Shield Expansion Board for Arduino is an Arduino shield which controls four stepper motors by using four A4988 stepper motor driver boards. The board’s pinout is compatible with open source CNC control firmware Grbl. While the pinout makes it possible for the board to be used as an Arduino shield, the board can also be controlled by external signals using the parallel male headers to drive the stepper motors. By that way the shield actually becomes a general purpose control board and can be interfaced with any microcontroller system.

Another good feature of A4988 Driver CNC Shield Expansion Board for Arduino is one of the motors can clone the movement of one of the other two motors. Since there are lots of CNC or 3D printer systems that have double motors for single axis, this feature makes the board a pretty good choice to be used with these systems.
