I have built a secure prototyping environment that I currently consider ideal.

Why ESP32, the trigger

The big one is an inexpensive chip that can use Wifi and Bluetooth.
Many examples, many code assets supported by Arduino, a lot of information, easy-to-understand manufacturer documents, ESP32 related kits such as M5Stack are also popular, so I chose it for both hobby and practical use.
While there are many personal cases, when we verify secure…
