I'm have a lot of experience with using Arduino/Arduino-like boards (MKR series, ESP8266/32, etc). for various designs. These are typically "one off" rather than for production. To date, power has been obtained through USB (wall wort) or an external PS. None require more than 1-2 Amps DC.
Some designs would be better (cleaner) if they could just be plugged in directly, or in some cases wired directly to 120VAC within an electrical wall box or enclosure.
I'm considering using an embedded miniature AC/DC power supply (they look like encapsulated relays). Obviously I would need to insure anything on the AC side is well insulated and protected from curious fingers if someone should open the enclosure.
Do you see any other safety issues that I'd need to be concerned about or best practices?
Thank you.
