Arduino CNC shield v3 engraving machine expansion board 3D printer A4988 driver board
This expansion board can be used as a drive expansion board for engraving machines, 3D printers, etc. There are a total of 4 slots for stepper motor drive modules. Can drive 4 stepping motors, and each stepping motor only needs 2 IO ports, that is to say, 6 IO ports can manage 3 stepping motors very well, it is very convenient to use, farewell The operation of traditional stepping motors is cumbersome.
