Hmm interesting. I'll have to dig more into this chip to see what it's about. I know the ESP32 is usually avoided when battery life is a high consideration, I haven't really played around with anything other than a few ardunos and the ESP8266 so I don't have much to compare it with. I guess I've just seen so many projects where someone tagged on an ESP chip to an arduino project just to get wireless capabilities with no understanding that the ESP series is quite a lot more powerful than the arduinos (some people I've talked to literally had no idea the ESP chips were programmable microcontrollers) so it's easy to jump the gun and assume that's what is happening in other projects also.
