Conclusion
When choosing a single board computer, consider your specific needs such as processing power, RAM, connectivity options, and intended applications. The Raspberry Pi 4 Model B remains a favorite for general use, while boards like the Rock Pi 4 and Odroid-C4 provide more power for demanding applications. Always check for the latest prices and availability as prices can fluctuate.
Favorite SBCs
My favorite SBC would be the Odroid XU4, which runs on a Samsung Exynos5422 2.0GHz Octa core CPU, 2GB LPDDR3 RAM, USB 3.0, Gigabit Ethernet, and support for hardware cryptography, all for a more affordable price. The Raspberry Pi 3 comes in second place due to its large and active community support. Other notable mentions include the Asus Tinker Board, Rock64, Banana Pi, and Orange Pi. While Banana Pi and Orange Pi provide a good balance between cost and performance, their poor community support can be a downside.
