High Light	A4988 Driver Expansion Board ，IO Ports Driver Expansion Board ，V3 Engraving Machine Pcb Board

This expansion board as a driver expansion board, can be used for engraving machines, 3D printers.

It is a total of four slots, can drive four A4988 stepper motor. Each road stepper motors only need two IO ports. In other words, six IO ports can be well managed three stepper motors. Very convenient to use.

Two, UNO for module IO port correspondence introduction.

IO corresponding figure above

UNO--------------------- expansion board

8 ------------------------ EN ( stepper motor driver enable , active low )

7 ----------------------- Z.DIR (Z -axis direction control )

6 ----------------------- Y.DIR (Y -axis direction control )

5 ----------------------- X.DIR (X -axis direction control )

4 ---------------------- Z.STEP (Z -axis stepper control )

3 ---------------------- Y.STEP (Y -axis stepper control )

2 ---------------------- X.STEP (X -axis stepper control )

/ / The following is a simple stepper motor control procedures,

# define EN 8 / / stepper motor enable , active low

# define X_DIR 5 / / X -axis stepper motor direction control

# define Y_DIR 6 / / y -axis stepper motor direction control

# define Z_DIR 7 / / z axis stepper motor direction control

# define X_STP 2 / / x -axis stepper control

# define Y_STP 3 / / y -axis stepper control

# define Z_STP 4 / / z -axis stepper control

/ / Function : step . function: to control the direction of the stepper motor , the number of steps .

/ / Parameters : dir direction control , dirPin corresponding stepper motor DIR pin , stepperPin corresponding stepper motor " step " pin , Step number of step of no return value.
