LEARN AND DOCUMENTS
I love this tiny device! There is so much tech crammed into this perfectly designed form factor, it blows my mind. I have been using mine to work on development of AtomVM - an exciting new development platform that runs Erlang and Elixir on the ESP32 (project can be found on GitHub), and this has been the perfect device to keep with me so I can continue development work when I travel. There are so many potential uses for this device using just the onboard peripherals I look forward to exploring all of those possibilities.
