EDIT: In April 2022, the Raspberry Pi foundation no longer allows default passwords on Raspberry Pis. Therefore,
instructions as written originally here no longer work. I have modified them slightly to show how to complete the
headless setup using the new Raspberry Pi imager. The original text still appears, but is struck out.
Today’s post is about setting a Raspberry Pi running the 64-bit Raspberry Pi OS for classroom use. This setup is very portable, uses very few cables, and costs about $60.
