Description



It has in total 4 channel slots for A4988 stepper motor driver modules (not included) for driving 3 channel of stepper motors.3D printer stepper motor driver can be used as driver expansion board for engraving machines and 3D printers. 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.
