Hello,
I’m the creator of AtomVM project 
You are right, AtomVM stills lacks a lot of features that users would expect such as maps and funs, but I’m actively developing it so they will be supported in near future
Right now I’m working on some improved garbage collection algorithms, while in the meantime I’m also implementing more BIFs and NIFs and reworking ESP32 platform support (bidirectional UDP support is coming).
I think soon I will write a post that explains how to blink a led using some Elixir code (it is already possible but not really well documented).
Hope you’ll find this useful.
