The Me Stepper Driver V1.0 is a easy to use stepper motor driver board based on chip A4988, generally used to drive bipolar stepper motors precisely. It is perfect for 3D printing, CNC, Makeblock Music Robot as well as a lot of other applications where it's necessary to control precise movement.
The A4988 is a complete microstepping motor driver with built-in translator for easy operation. It is designed to operate bipolar stepper motors in full-, half-, quarter-, eighth-, and sixteenth-step modes. Plus, we add a on-board DIP Switch and a on-board potentimeter, so you can change step modes and the current of motor easily.
