Hello, from other posts on this forum I already know that I can power 5V devices simply by connecting them to the VBat (in particular I'm thinking about relay module).

Can I use some 3.3V sensors with Espruino at the same time? And should they be connected to a separate GND line?

Yes, you can use both - there shouldn't be any need for a separate ground line at all.
