A, Product introduction
The expansion board can be used as a carving machine,3DPrinter driver expansion board, a total ofFourThe slot of the drive module of the stepper motor.Note that Moto Sako does not containA4988Stepper motor drive module, need to be in the shop to buyCan be drivenFourThe road does not enter the motor, and each step motor is only requiredTwoindividualIOMouth, that is to say,SixindividualIOMouth can be a very good managementThreeStepper motor, the use of very convenient, farewell to the traditional stepper motor cumbersome.

Two, UNOAnd moduleIOIntroduction to the correspondence of the mouth



Stepper motor basic control needs of the pin, the other pin is in the engraving machine, or3DThe printer when it is used, here we do not make detailed,IOCorresponding as above.
