I've been wanting to play around with the esp32's for a while.  They're very popular in home automation / home assistant circles as they kind of allow all sorts of things to just run out of the box.  This might be the product that gets me to play around with them.

“Nano ESP32 brings MicroPython and IoT to the fingertips of Arduino user” – this is how Arduino describes their software and hardware compatibility. They believe that their new Nano ESP32 module is the best platform to learn MicroPython.
