The Calliope mini is a single-board computer developed for educational usage at German primary schools. The goal of the initiative is to provide all pupils as of grade three of primary schools in Germany with a Calliope mini free of charge.
Background Calliope mini was inspired by the BBC micro:bit, which was distributed to pupils of grade seven in the United Kingdom. The non-profit Calliope gGmbH is responsible for developing and maintaining the Calliope mini.
The name "Calliope mini" is a reference to Kalliope, a daughter of Zeus and the muse who presides over eloquence, science and epic poetry.
