Brand: KeeYees

Features:

• Stable performance A4988 Driver Chip is low power consumption and will not be too hot during use. The performance is more stable than chip.
• DC Power cable The DC power cord can quickly connect to the DC power adapter and power the CNC shield board. Save time and more securer cable connection Plug and Work.
• CNC Shield This is the latest version of the expansion board, which can be used for engraving machines and 3D printers. It can drive 4 A4988 stepper motors.
• With 20 Pcs Jumpers When setting up CNC projects, jumper caps are necessary accessories. There are 20 of them in the kit, enough for most project.
• Reliable technical support Please visit github (github: Keeyees/KY-102) to get relevant information or can contact us on Amazon, we will send PDF Document to you.

Part Number: CNCA4988

Details: CNC Expansion Board:
– GRBL 0.9 compatible
– Runs on 12-36V DC
– 4-Axis support: X, Y, Z
– It can drive 4 stepper motors, and each stepper motor only needs 2 IO ports.
That is to say, 6 IO ports can manage 3 stepper motors very well, which is very convenient to use.
