A full version of the Wolfram Language is available for the Raspberry Pi computer and comes bundled with the Raspbian operating system. Programs can be run from a Pi command line or as a background process, as well as through a notebook interface on the Pi or on a remote computer. On the Pi, the Wolfram Language supports direct programmatic access to standard Pi ports and devices.
