Arduino-compatible boards

Although the hardware and software designs are freely available under copyleft licenses, the developers have requested that the name "Arduino" be exclusive to the official product and not be used for derivative works without permission. The official policy document on the use of the Arduino name emphasizes that the project is open to incorporating work by others into the official product.^[2]

As a result of the protected naming conventions of the Arduino, a group of Arduino users forked the Arduino Diecimila, releasing an equivalent board called Freeduino. The name "Freeduino" is not trademarked and is free to use for any purpose.^[65]

Several Arduino-compatible products commercially released have avoided the "Arduino" name by using "-duino" name variants.^[65]

Software-compatibility only

These boards are compatible with the Arduino software, but they do not accept standard shields. They have different connectors for power and I/O, such as a series of pins on the underside of the board for use with breadboards for prototyping, or more specific connectors. One of the important choices made by Arduino-compatible board designers is whether or not to include USB circuitry in the board. That circuitry can be placed in the cable between development PC and board, thus making each instance of the board less expensive. For many Arduino tasks, the USB circuitry is redundant once the device has been programmed.
