I was told that the Arduino name is trademarked so I can’t use it without paying a license and have the written approval from the Arduino team. I mistakenly thought that if the word Arduino is used in conjunction with other words is ok. So I have changed the name of the board to Robot Builder’s R-duino. I will order new boards with this name and also with a few other improvements in the following week. Until I get them in stock, no kit will be sold that contains boards that wrongfully use the Arduino name.
Apologies to the Arduino team and thanks for understanding.
