Isn't there a proper way to tell the ESP32 to just terminate all execution and quit (until power cycle).

Looking for an ESP32 S3 just with more pins...

So since there are a plethora of ESP32 boards :o it's better if I ask.

I started developing a project with the XIAO ESP32S3: https://wiki.seeedstudio.com/xiao_esp32s3_getting_started/

One thing I do know for a fact that this board is rock solid I running a stress test for my code on it since many ...

Interfacing the ESP32S3 with some 5V sensors

Hello,

I migrating an old Arduino project to ESP32S, this concurrently uses 5V sensors for everything. I wonder if these sensors can be all hooked up or need TTL conversion, here is the list:

1, HC-SR04 Ultrasonic Sensor, According to this tutorial this sensor can be hooked up no problem to the ...
