Fuhjythy 4-Lead Nema17 Stepper Motor 17HS4401S + CNC-Shield V3 Engraving Machine+4pcs A4988 Driver Expansion Board 3D Printer Kit

Stable performance A4988 Driver Chip is low power consumption and not be too hot during use. The performance is more stable than chip. Adopting a movable A4988 compatible stepper driver. (A4988, DRV8825, and others) CNC V3.0 GRBL 0.8 -c compatible. (Open source firmware- running on can convert G-code-commands into step signals) 4- support (X, Y, Z, a can copy X, Y, Z or create a complete 4- custom firmware- using pins- D12 and D13); 2 endpoints per (total of 6) - set microsteps for stepper drivers-. (Some drivers, such as DRV8825, can execute -1/32 microsteps)The stepper motor can be connected to a 4pin-Molex connector or welded in place. Operates on 12-36V DC-power. (Currently, only the -DRV8825 driver can handle voltages up to 36V, so please consider the working voltage when supplying power to the circuit board.)
