KeeYees Professional 3D Printer CNC Kit with E-Tutorial - CNC Shield Expansion Board V3.0 Board A4988 Stepper Motor Driver DC Power Cable Mechanical Switch Endstop with Jumper caps

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. A4988 Stepper Motor Driver: - Size: 20*15*11mm - Heat Sink Size: 9*9*5mm - Minimum operating voltage: 8V - Maximum operating voltage: 35V - Continuous current per phase: 1Av - Maximum current per phase: 2A - Minimum logic voltage: 3V - Maximum logic voltage: 5.5V - Thermal shutdown circuitry - Ground fault protection - Load short-circuit protection - Microstep resolutions: Full, 1/2, 1/4, 1/8 and 1/16 KeeYees Board: - microcontroller - Input voltage: 7-12V - 5V Electric current: 500MA - 3.3V Electric current: 50MA - 14 Digital I/O Pins (6 PWM outputs) - 8 Analog Inputs - 32k Flash Memory Package included: 1 x CNC Shield Board 1 x KeeYees Board 4 x A4988 Stepper Motor Driver with Heat Sink 1 x Female DC Power Cable 4 x Mechanical Switch Endstop 20 x 2.54mm Black Jumper Caps

• ★ 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.
