I'm not sure that the RK3688 and a big chunk of the article spent on its specs belongs in a "State of Embedded: Q4 2025 Overview" given that it's due sometime in 2026. I'm sure it's going to be great but I suggest it belongs to a future state.
On the other hand, CIX have been putting actual Arm v9 hardware in developers' hands for some time.
Fun story: my wife ordered a couple of those "alternate" sets, and none inflicted on Legos patent nor TM (no lego branding, not a copy of a lego set, etc). The Swedish customs acted on their own (baffling to me) and stopped the package, sent her a letter in stark wording to accept forfeit. She challenged this, then Lego's lawyers got in contact with us and, using the figure patent, claimed this was a copy and we should forfeit or they would sue her. Very harsh letter, very stark wording.
Left a very bad taste in my mouth, haven't bought any Lego (or alternatives either) since.
