CNC Shield V3 A4988 Driver Expansion Board | Modules | Expansion

This is CNC Shield V3 A4988 Driver Expansion Board from the category Modules | Expansion.

As a driver expansion board, this board can be utilised with 3D printers and engraving machines.

There are four slots in all, and each one can power an A4988 stepper motor. Only two IO ports are required for each road stepper motor. In other words, three stepper motors can be efficiently managed by six IO ports. Very user-friendly.

Introduction of UNO for module IO port correspondence.

Note: The A4988 module and the UNO R3 module are not included in this version.
