V3 Extension Board, CNC Shield Expansion Board with 4pcs A4988 Stepper Motor Driver Heat Sink for Engraver 3D Printer DC 12V to 36V
V3 Extension Board, CNC Shield Expansion Board with 4pcs A4988 Stepper Motor Driver Heat Sink for Engraver 3D Printer DC 12V to 36V
Package Includes: 1 x V3 Extension Board4 x Drivers4 x Heat Sinks Read more CNC Expansion Board: Version: V3.0Size: 68 x 53 x 18mm / 2.67 x 2.08 x 0.7"Voltage: DC 12V to 36V (only DRV8825 driver can handle up to 36V, so please consider voltage for power supply)The V3.0 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, which can drive 4 stepper motors, and each stepper motor only needs 2 IO ports, that is to say, 6 IO ports can manage 3 steppers The motor is more convenient to use.Experimental phenomenon: The stepper motor reverses one circle, pauses for 1 second, and then rotates forward one circle, and so on.Note that when connecting the A4988 module, do not connect it backwards. The wiring of the stepper motor is: 2A, 2B are a group (red, green); 1A, 1B are a group (blue, yellow). If you want to change the direction, you can change the position of one group, such as swapping 2A and 2B.
