This really begs the question as to how much juice you can get from $5 compute.
This IS IoT in my opinion, not whatever bloatware comes with your Samsung fridge or wifi-connected faucet.
There's very little compute going on in this chip. It's a few hashes per second. Which is to say you can do a lot with $5 of compute if you can figure out how to not need to use a lot of compute.
A pregamgamanagany test can be $5 and apparently it can run doom, so in bulk compute has to be pretty cheap.
> $5 compute
Unrelated but the author at Tom's Hardware is apparently unaware of AliExpress so they bumped the price from $2 (or less) to $5. And that's the price for just one. These things are so cheap you can throw them in everything. They're the perfect alternative to a Raspberry Pi because they have WiFi, Bluetooth, lots of GPIO, and decent compute. Not enough to run Linux but you don't need Linux for IoT.
