Twotrees CNC Controller Kit with Nema 23 Stepper Motor 8.0，TB6600 Stepper Motor Driver,GRBL CNC Shield Board，Switch Endstop

Probably my mistake in reading the contained parts, but I thought that I was getting an arduino board in this kit. There was not one included. Probably not a good idea to show one in the promotional picture of the kit if there isn't one actually in it. One of the pictures is even an image of the Arduino board on it's own, as if it is part of the package. I already have on, so this is not a problem for me, though I had not intended to use the one I have for this kit. Everything arrived quickly and packed up nicely. Very happy with the components so far, still need to play around with them though.

This is certainly a nice kit for the price, but a wiring schematic would have been helpful. The Arduino board works, but yielded erratic performance, so finally I replaced it with a real Arduino and it solved all my problems. The motors work great and I guess I got what I paid for with the cheap Arduino.

Just perfect for some mid range hobby projects. I'm using them to build a new CNC and this kit covers just about all the electronics except for the power supply. The limit switches with pull up resistor and capacitor was a bonus. I ended up getting two sets so I have something for another project. ;-)

Everything assembled & operated properly. A couple of reviews indicated they expected a genuine "Arduino" Uno. The picture only shows "Uno", which indicates that's its a compatible model as all of the 3rd party versions I've come across do. If it were an "Arduino" Uno, the kit would be more expensive.
