Banana Pi is now selling the BPI-M2S, a single-board computer that it teased over a year ago. The Banana Pi BPI-M2S is available with a choice of two Amlogic SoCs, both with 4 GB of RAM and an HDMI 2.1 port, plus expansion options.https://www.notebookcheck.net/Banana-Pi-BPI-M2S-launches-for-under-US-100-in-two-SoC-variants.676100.0.html
Here's an idea. Maybe run a comparison between all these SBCs? Features, use cases and applications (home assistants, routers/ad blockers etc).
