Intel Edison

Intel(R) Edison is a dual-core Silvermont Atom(TM) clocked at 500MHz. The Edison also features 4GB of storage, 1GB ram and on-board WiFi and Bluetooth.

Currently supported boards:

UART

On both the Arduino board and the breakout board, The available UART interface is on /dev/ttyMFD1

Intel Arduino board

The Edison used with the Arduino board has the following limitations in libmraa:

Because of the way IO is setup with the tristate on the Arduino breakout board IO will be flipped as it is setup. It's recommended to setup IO pins & direction before using them in a setup() method or similar. It's impossible on this platform to avoid some GPIOs flipping on setup.
