If you want to replace your Raspberry Pi 4 with an alternative, whether because of scarcity or because you want slightly different performance, there are a number of single-board computers available. The Raspberry Pi Foundation is developing wonderful tools with a huge community and have opened the door to numerous development boards for various projects (IoT, server, Microcontroller, DIY, etc.). We recommend using Raspberry Pi products for beginners because of the size of the community and the online help available.

In this article, we present some models that are close to the Raspberry Pi. There are many more.

N.B: click on the images to scroll through the information on each card. A summary table is available at the end of the article.
