Stable performance A4988 Driver Chip is low power consumption and not be too hot during use. The performance is more stable than chip. CNC V3.0 GRBL 0.8 -c compatible. (Open source firmware- running on can convert G-code-commands into step signals) 4-axis support (X, Y, Z, a can copy X, Y, Z or create a complete 4-axis custom firmware- using pins- D12 and D13); 2 endpoints per axis (total of 6) Adopting a movable A4988 compatible stepper driver. (A4988, DRV8825, and others) - 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.)
