描述
- 【Better cooling effect】Brushless DC Cooling Fan can dissipate heat for 4 drives at the same time and enhance the heat dissipation effect better than the heat dissipation aluminum block. The CNC shield module has a 5V power interface, which can directly supply power to the cooling fan. In addition, the set comes with screws and fixed copper posts. There are special fixing holes on the CNC shield, which can easily fix the cooling fan above the drive chip.
- 【DC Female Power Connector】The adapter can quickly connect the DC power adapter. Save time and more securer cable connection Plug and Work.
- 【CNC Shield Module with Free 20pcs Jumpers】This is the latest version of the expansion board, which can be used for engraving machines and 3D printers. It can drive 4 A4988/DRV8825 stepper motors. The jumper caps are necessary for CNC setups. You do not need to purchase this part extra.
- 【DRV8825 Stepper Motor Driver w/ Heat Sink】DRV8825 is upgrade of A4988! It is a must-have module for 3D printers, CNCs and engraving machines. The 4-layer PCB board has better heat dissipation performance.
- 【Reliable technical support】If you don't have a CD drive, please visit our website( www.keeyees.com ) to get relevant information or can contact us on , we will send PDF Document to you.
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. Brushless DC Cooling Fan: - Rated voltage: DC 5V - Working voltage: 3.0-5.8V - Current: 0.15A - Air volume: 5 m³ / h - Number of revolutions: 13200RPM - Noise: 18 dB DC Female Power Connector: - Material: Zinc Alloy and Plastic - External Diameter of the Plug: 5.5mm - Internal Diameter of the Plug: 2.1mm DRV8825 Stepper Motor Driver: - Applied for driving stepper motors up to 8.2V-45V 2.5A - 4-layer PCB board (better heat dissipation) - 6 different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step Package Contents: 1 x CNC Shield Board 1 x KeeYees Board 4 x DRV8825 Stepper Motor Driver with Heat Sink 1 x Brushless DC Cooling Fan 1 x Female 12V DC Power Connector 20 x 2.54mm Black Jumper Caps 1 x 1.5m USB cable
