Selling Arduino compatible products

It is possible to sell boards derived from the Arduino design as long as these rules are followed

  • The product can't contain the name Arduino
  • The board can't have Arduino written anywhere on it
  • The board must not copy the Arduino Logo or graphic design
  • The auction/website title can't use the Arduino name
  • You can write in the description that the board is derived from Arduino.
  • You must explicitly say that you're not connected to Arduino and your product is a derivative
  • You must specify that any tech support request must be directed to you

ie. If you sell a sensor that is compatible with Arduino you can call it "XYZ sensor for Arduino" and NOT "Arduino XYZ Sensor"
