This kit mainly includes a keyestudio CNC V0.9A and three A4988 driver modules.

Keyestudio CNC GRBL V0.9 is a main board developed by Keyestudio for CNC, laser engraving machine, writing robots and other robots. It has complete interfaces with cost-effective and can be driven via external connection, suitable for DIY and factory use.

The A4988 is a DMOS microstepping driver with converter and overcurrent protection, which can operate a bipolar stepper motor in full, half, 1/4, 1/8 and 1/16 step modes, with output-driven performance up to 35 V and ± 2A. The A4988 also includes a fixed off-time current regulator that operates in slow or mixed-decay modes.
