$3 chipset in a $300 watch? I know there’s a lot more to the BOM but hard to get excited about this when the Apple Watch SE exists at the same price with better components, design, SDKs, support, etc.

at first this looked kind of intersting, but upon reading it's just another low cost, closed-source piece of throw-away tech. Most of these companies go out of business within a few years and abandon their products; if it's open source at least we can keep using them.
