The Raspberry Pi single board computer (SBC) is one of the most favorite SBCs in the market today. It's been around for about 13 years and lists ten versions to date (Feb. 2025). While the Raspberry 5 is the most recent version of the Pi and some versions are no longer manufactured (e.g., 1A+, 1B, 1B+), there are earlier versions of the Pi still in use today.
