There are 4-way stepping motor drive module slots in total. (note that this board does not include a4988 stepping motor drive module, which needs to be purchased separately in this store). It can drive 4-way stepping motor, and each stepping motor only needs 2 10 ports, that is to say, 6 10 ports can manage 3 stepping motors well, It is very convenient to use, and the traditional step motor operation is tedious.\u003c\/span\u003e \n\u003c\/div\u003e \n\u003cdiv\u003e\n    \n\u003c\/div\u003e \n\u003cdiv\u003e \n \u003cdiv\u003e \n  \u003cspan style=\"font-size: 16px;\"\u003eProduct description\u003c\/span\u003e \n \u003c\/div\u003e \n \u003cdiv\u003e\n     \n \u003c\/div\u003e \n \u003cdiv\u003e \n  \u003cspan style=\"font-size: 16px;\"\u003eThe basic control pin of the stepping motor, other pins are used when engraving machine or 3D printer, we will not explain in detail here.\u003c\/span\u003e \n \u003c\/div\u003e \n \u003cdiv\u003e \n  \u003cspan style=\"font-size: 16px;\"\u003eArduino uno ------ expansion board\u003c\/span\u003e \n \u003c\/div\u003e \n \u003cdiv\u003e \n  \u003cspan style=\"font-size: 16px;\"\u003e8 ------ en (step motor drive enable terminal, effective at low level)\u003c\/span\u003e \n \u003c\/div\u003e \n \u003cdiv\u003e \n  \u003cspan style=\"font-size: 16px;\"\u003e7 ------ z.dir (direction control of Z axis)\u003c\/span\u003e \n \u003c\/div\u003e \n \u003cdiv\u003e \n  \u003cspan style=\"font-size: 16px;\"\u003e6 ------ y.dir (direction control of Y axis)\u003c\/span\u003e \n \u003c\/div\u003e \n \u003cdiv\u003e \n  \u003cspan style=\"font-size: 16px;\"\u003e5 ------- x.dir (direction control of X axis)\u003c\/span\u003e \n \u003c\/div\u003e \n \u003cdiv\u003e \n  \u003cspan style=\"font-size: 16px;\"\u003e4 ------ z.step (step control of Z axis)\u003c\/span\u003e \n \u003c\/div\u003e \n \u003cdiv\u003e \n  \u003cspan style=\"font-size: 16px;\"\u003e3 ------ y.step (step control of y-axis)\u003c\/span\u003e \n \u003c\/div\u003e \n \u003cdiv\u003e \n  \u003cspan style=\"font-size: 16px;\"\u003e2 ------- x.step (step control of X axis)\u003c\/span\u003e \n \u003c\/div\u003e \n \u003cdiv\u003e \n  \u003cspan style=\"font-size: 16px;\"\u003eIt is worth noting that when plugging in a4988 module, do not plug in reversely.
