The Raspberry Pi Compute Module has gone through several iterations; it lacks the normal interface ports and functionality of a normal Pi, and is meant more for business and scientific users. I won't cover the versioning of this one in great detail but you can read more about the Compute Module on the Raspberry Pi website.

Raspberry Pi Foundation

This is the Raspberry Pi Foundation's first official microcontroller. It uses a custom chip made by the team known as the RP2040. It's the smallest board yet and one of the most flexible.

Finding the best Raspberry Pi for your project depends on your project needs. Consider factors like size, mobility, and necessity of each hardware component. In general, you’ll find the newer models have more power and features that open your Raspberry Pi projects to a myriad of potential.

For example, the Pi Zero is suited for small projects. We were able to fit the Pi Zero inside an old NES controller just to run RetroPie!

But the Pi 3 B+ is great for things like setting up a Raspberry Pi media server or Pi powered MIDI synthesizer.

If you want the latest and greatest—you may want to snag a Pi 4 to see what it's capable of while the Pico is an excellent choice for anyone who needs a low-power unit for simple control processing.
