if you have modified the core files or one of the libraries you must make your modifications available to everybody * The programs written on Arduino are yours. * If you build your circuit as a shield that plugs on top of an Arduino board all the circuit is yours and you don't have to release anything * if you have made your circuit as a derivative of the Arduino board you must release the design files with a CC-BY-SA license like the original cad files You can use Arduino to make a commercial product following some simple rules. Additionally, see the previous question for information about the use of the name “Arduino”.Ī summary in plain English from Arduino forum In all cases, the exact requirements are determined by the applicable license. It does not prevent the sale of derivative software or its inclusion in commercial products. The source code for the Arduino environment is covered by the GPL, which requires any modifications to be open-sourced under the same license.

Any modifications to the core and libraries must be released under the LGPL. The LGPL does, however, require you to make available object files that allow for the relinking of the firmware against updated versions of the Arduino core and libraries.

Using the Arduino core and libraries for the firmware of a commercial product does not require you to release the source code for the firmware. You may manufacture and sell the resulting product. Physically embedding an Arduino board inside a commercial product does not require you to disclose or open-source any information about its design.ĭeriving the design of a commercial product from the Eagle files for an Arduino board requires you to release the modified files under the same Creative Commons Attribution Share-Alike license. Can Arduino be used in commercial products?
