Controller enclosure
The controller enclosure protects the controller board from accidental short circuits and physical damage while keeping everything neat.
There are no recommended enclosures at the moment. A cost-effective way is to get a commercial off-the-shelf (COTS) enclosure or junction box that is large enough to hold your board.
Another option that might be a better fit is to design an enclosure and and 3D print it.
If you know of a good COTS enclosure, please suggest.
