context_page_description: This is a non-exhaustive list of Arduino boards and compatible systems. It lists boards in these categories:
  Released under the official Arduino name
  Arduino "shield" compatible
  Development-environment compatible
  Based on non-Atmel processors
  Where different from the Arduino base feature set, compatibility, features, and licensing details are included.
context_section_description: 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.
