CNC Shield V4.0 can be used as a drive expansion board for engraving machines, and needs to be used with Arduino NANO. There are 3 slots in the board for stepper motor drive modules, can drive 3 stepper motors, and each stepper motor needs two IO ports, that is, 6 IO ports can drive three stepper motors very well, it is very convenient to use.
CNC Shield V4.0 has a GPIO of Arduino NANO, it is convenient to connect other modules, such as limit switches. In addition, CNC Shield V4.0 also has an I2C interface, you can connect an LCD display with I2C interface.
The input voltage of CNC Shield V4.0 is DC 7.5V-12V, do not exceed 12V.
