  1. When I initially commented I clicked the “Notify me when new comments are added” checkbox and now each time a comment is
    added I get several emails with the same comment.
    Is there any way you can remove people from that service?

    1. Is there an Unsubscirbe URL in e-mails?

      We are trying to solve it, once we fix it, We will notice you

  2. There have been a few links from this site that I have licked on and it does not show some of the tutorials. I have bought a few of these units and would like to see more options on things we can do other than just the kits. The kits are ok, but I would like to make more custom things like I do with Arduino or Raspberry PI. Also is there any other control software that we could use other than mDraw for other CNC machines?

    Thank You

  3. Please do correct the mCore specification!

    Its microcontroller is Atmega 328, not 238 as stated everywhere on your website.

    You have it right on the schematic.

    1. Hi tyimofej,

      Great thanks for your remind. We are so sorry for this kind of mistake.
      Will feedback and correct these mistakes. Thanks again!

      Best Regards!

  4. Thanks for sharing your ideas. I would also like to convey that video games have been ever before evolving. Technology advances and inventions have assisted create practical and active games. These entertainment video games were not that sensible when the actual concept was first of all being experimented with. Just like other kinds of technologies, video games also have had to develop through many ages. This itself is testimony for the fast growth of video games.

  5. Hi,

    how can i turn on the LED RGB onboard from Arduino IDE Programming?

    I try out with the examples, but, only came for “PORT_X” not on board, thanks for yor replay.

    1. Hi Mike,

      You can turn on the onboard RGB LED with mBlock software. It is suggested to program with mBlock software since it is much easier.
      After you edit the mBlock program, you can refer to its generated arduino program have a try.
      If you want to program with Arduino software, you may need to figure out the pinouts on the board to program by yourself.
