That's what esp32's are for. $5 and uses fuck all power.
While people do often use pis to do things you could do with an esp32, an ESP32 cannot do the majority of things a Pi can do.
Personally I use ESP32s for GPIO to control things around the house and have one Raspberry Pi acting as a hub.
In some of the tinkering applications, RPis are shoehorned into the very operarional model that is followed by ESP32s.
ESP32s may be harder to debug but they allow us to remove a big chunk of the complexity that lies between our code and what we want the device to do.
I think your criticism is more in line with "they are not exactly the same as RPis". And that is fine.
I chose my wording very intentionally. My criticism is exactly what I said.
It’s like comparing a bicycle to a light duty farm truck.
Do you need a full blown Linux desktop to blink a led light? Or drive a servo? Or even have a HTTP server? No.
Microcenter sold it for $5, limited to 1 per customer. Additional ones were $15 each.
It was a wonderful time to live nearby.
A pi zero is to play with, an esp32 is so tiny, that it is more of a build for a single thing, and then set it and forget it doing that single thing.
You cant really stack more and more cool stuff onto it and keep building on it.
Then I just pull in all my components. The ones I use will get compiled, the ones I don’t won’t.
Mostly works fine. Eventually you will run out of NVRAM to save binaries on, but another esp-32 is like $3.
