Do not use the word Arduino in any part of the name of the board. You can mention the Arduinoness of the board in the description but not the name. Also make it look different, have say a red or green solder mask in place of the blue, do not have the same markings on it. Do not put the FCC symbol on it because although you think it is the same design FCC will not.
Thank you very much for your reply,But I double check the arduino FAQ,There is declear as below:
What should I call my boards?
If you're making your own board, come up with your own name! This will allow people identify you with your products and help you to build a brand. Be creative: try to suggest what people might use the board for, or emphasize the form factor, or just pick a random word that sounds cool. "Arduino" is a trademark of Arduino team and should not be used for unofficial variants. If you're interested in having your design included in the official Arduino product line, please see the So you want to make an Arduino document and contact the Arduino team.
While unofficial products should not have "Arduino" in their name, it's okay to describe your product in relation to the Arduino project and platform. Here are a few guidelines that explain which uses we consider reasonable. Not okay:
Arduino Compatible Xxxxxx - use "Xxxxxx (Arduino-Compatible)" instead Okay:
Xxxxxx for Arduino - products that work with official Arduino boards (e.g. shields or kits)
Xxxxxx (Arduino-Compatible) - variations and clones which are software and hardware compatible
Note that while we don't attempt to restrict uses of the "duino" suffix, its use causes the Italians on the team to cringe (apparently it sounds terrible); you might want to avoid it. (It's also trademarked by a Hungarian company.)
So,could you tell me,Can I name my board XXXXXXX(Arduino-Compatible)
Thank you very much.
