A very excellent design board for the Mesh networks using sub GHz!
I am now waiting for a case for it and for the Super IO!
Awesome little node! I only regret buying just one. Still building out the mesh near by myself, and it’s 22db tx, so hard to say how well it’s doing, but I’m making contact. Very responsive unit overall. (Buying number 2 soon!)
For a project I was researching and came over your page and found just what I wanted. Order on Friday and received it on Monday morning in Berlin Germany.
Thanks a lot
Got the Muzi Duo about 2 weeks ago with the Super IO. Love it, though the one thing that would make this better is being able to run both 2.4 Ghz and 915 Mhz antenna at the same time (might just be a software limitation). Ended up designing a case with a friend and so far it is running smoothly and it’s built to last.
Amazing just need a stl for a case for the super io
