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.[1]

Background

Calliope mini was inspired by the bit, which was distributed to pupils of grade seven in Great Britain. The Calliope gemeinnützige GmbH is responsible for developing and maintaining the Callipe mini.[2] The name "Calliope mini" is a reference to Kalliope, a daughter of Zeus and the muse who presides over eloquence, science and epic poetry.[3]
