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.[13]
Several Arduino-compatible products commercially released have avoided the "Arduino" name by using "-duino" name variants.[13]
The following boards are fully or almost fully compatible with both the Arduino hardware and software, including being able to accept "shield" daughterboards.

These boards are compatible with the Arduino software but 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.

Arduino boards have several distinctive attributes. One is the distinctive headers, and another is the Arduino Language. The header location, and signals are essential to accept shield daughter boards, and hence be an Arduino footprint-compatible board. Many Arduino compatible boards use one of the two Atmel ATmega processor families used in Arduino UNO or Arduino Mega 256. This allows them to use the Arduino IDE, which includes the Arduino Language and so provide Arduino software compatibility.
Boards that do not use an Atmel ATmega may implement Arduino shield compatibility, or Arduino software compatibility, or both. Some incompatibility results in variations from the microcontrollers of the Atmel ATmega families used on Arduino boards.[19] Arduino boards themselves have small variations. For example the Arduino UNO and Arduino Mega 256 are not identical in all respects; the Arduino Mega256 provides I²C on pins 20 and 21, and Arduino UNO provides I²C on on pins A4 and A5.
The following non-ATmega boards accept Arduino shield daughter boards. The microcontrollers are not compatible with the Arduino IDE, but do provide a version of the Arduino IDE and compatible Arduino language software libraries.

The Maple IDE includes both an implementation of the Arduino Language, and lower-level native libraries (with support from the libmaple C library). |
| Microchip chipKIT Uno32 and chipKIT Max32 | PIC32 | USB | Digilent | 32-bit MIPS-M4K PIC32 processor boards. The Arduino libraries have been implemented natively for the PIC32 and these kits run in a fork of the standard Arduino IDE chipKIT32-MAX and are compatible to most shields.[20][21][22] |
The following boards accept Arduino shield daughter boards. They do not use ATmega microcontrollers and so are not compatible with the Arduino IDE, nor do they provide an alternative implementation of the Arduino IDE and software libraries.
