Raspberry Pi
The Raspberry Pi is a popular single-board computer designed to promote the teaching of computer science in schools. The use of the Raspberry Pi computer ranges from robotics to home automation. Many variations of the Raspberry Pi exist, such as the Raspberry Pi Zero, which is smaller than the more powerful Raspberry Pi 4.
