Feature

●Use removable A4988 or DRV8825 compatible stepping driver: This CNC shield expansion board is designed to work with A4988 or DRV8825 compatible stepping drivers. These drivers are widely used in CNC machines and 3D printers to provide reliable and precise control for your stepper motor
●Expansion Board can be used as a Engraver or 3D Printer Driver: This versatile expansion board can be used as driver for both engraving and 3D printers. The stepping motor moves are controlled so you can accurately positioning and precise engraving or printing
●GRBL 0.8 COMPATIBILITY: CNC Shield expansion board is compatible with GRBL 0.8, the open source firmware commonly used in CNC machines and 3D printers. Converts G-code commands to define motion and motion into stepping signals that control motors
●Open Source Firmware: The GRBL firmware used in this expansion board is an open source. This means that source code is free to change or customize. This allows the firmware to be adjusted to your specific needs and adjusted accordingly
●PWM Spindle and Direction Pins: The expansion board has PWM spindles and direction pins to control the speed and direction of the spindle or motor. This allows for precise control of the cutting or engraving process


Description

Features:
Use a removable A4988 or DRV8825 compatible stepping driver.
Expansion board can be used with engraving machines or 3D printer drivers.
Compatible with GRBL0.8. Open source firmware to convert G code commands to stepping signals.
PWM spindle and direction pin, 4 shaft support (copy X, Y, Z, A-X, Y, Z, or use pin D12 and D13 to customize firmware to perform a complete shaft 4)
The stepping motor with a compact design can be connected or soldered.
This is a set of disassembled parts and requires basic soldering skills to solder them together.
