No, that is at best partially incorrect. Worst case wrong. Esp32-s2 has 3 low power sleep suspend modes. For the speed of the dual 240mhz processors are monste

No, that is at best partially incorrect. Worst case wrong. Esp32-s2 has 3 low power sleep suspend modes. For the speed of the dual 240mhz processors are monsters with ~4mb of ram. Xtensa core is among best in class, but could be overkill for the application wheres STM, etc. might have a smaller much lower frequency chip that is. A lot of the esp32 dev boards also have bigger than necessary "protect the processor" type components which burn power too. Raspberry pi burns way more power than esp32 per clock cycle (its a little toaster) but nobody complains about that. I suspect the complaints are by hobbyists using arduino on s2 which can't/dont access them. (requires c++) Riscv as architecture is not power efficient yet, give it time - the fact riscv exists at all still blows my mind.
