There are plenty of other chipsets that are lower in power consumption than ESP32. Raspberry Pi does provide the Pico 1 and Pico 2 for embedded stuff which is mostly great. Don’t know if they fixed the errata 9 on the Pico 2 yet with the leaking GPIO thingy.
STM32, AVR based stuff, PIC, ESP32, Pico’s. We got a lot of fun stuff to tinker with.
It is that many are familiar with them, they have good support, fairly extendible and great community.
Also used in commercial solutions for those exact reasons.
There is cheaper and better hardware but the RPi has a bit of a goldilocks position.
