  yes as others have said. microcontroller with decent io and wifi, fairly easy to make web interfaces which is handy. A step up from arduino and i dont think it eats too much more power if the wifi is used sparingly. I've got a wildlife infrared camera made off a pi zero. I reckon if i can switch that to esp32 the battery life might stretch quite a bit - or i can shrink the case to a smaller battery. raspberry pipico would probably do similar tbf, but i bought like 10 esp32 for cheap....

  I think esp32 is more commonly used. i think they're pretty similar capabilities and both dirt cheap. I just see more projects with esp32.

  Might make open source more trustworthy, It can't be any harder to check than closed source.
