Your cart is empty. 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

I knew nothing about Arduino programming before I purchased this. I have a project that needs to control two stepper motors. This kit works well for my project. I downloaded the instruction in pdf and followed the instructions. I watched a few youtube to understand how CNC shield works. I have my stepper motors up and running in 2 days.A few improvements on the instruction manual will be perfect. Need instructions on how to use the endstop RAMPs. For $30, it's a good deal.

One of the A4998 stepper motor drivers were damaged/dead out of the box. Was planning on upgrading them either way.

This is great. Used this as the core backbone for converting my spare 3D printer into a CNC machine. Using grbl for the gcode files and only needed to do a few tweaks and boom goes the dynamite. Recommend

you get what you pay for. two parts malfunctioned but overall still worth the price.

I chose this set because the description claims to be GRBL V0.9+ compatible. It is not. There was a hardware change with GRBL V0.9+ and when I run the current GRBL with this board, the Z limit switch doesn't work. This board should work with V0.8 and below but that is not what I need. This is one of the only listings that claimed V0.9+ support so I bought it even though I'm using different drivers.When it arrived, the pins and headers were all bent. Since I really needed this set thinking it was GRBL 0.9 compatible, I decided to bend the pins/headers back into place and attempted to use it. I was able to run the motors but the Z limit switch didn't work. I've had trouble with other Amazon CNC shields and have since learned about the hardware change with v0.9. I'm very disappointed that the claim was incorrect. I am returning this set since it was damaged and doesn't work as it claimed. If you're looking for GRBL V0.9+ compatibility, look for CNC Shield V3.51.

Lasted all of about 1 hour total runtime. Bench testing unit, motors quit moving. Tried different motors, different drivers, different power supply. Motors will not move anymore. Period.No idea what I did or didn't do, was working just fine on the bench with grbl 1.1 installed onto Arduino and open builds control and UGS for the interface.Weird.

Set up for a Cnc configuration and it works well.

Great value. You get alot for a very good price. Everything comes packaged well and everything is included as detailed.Fast delivery and good response from supplier.Product did not work properly out of the box. Problems with some of the motor channels resulting from poor workmanship and quality testing.
