@wschnell 在 Connecting multiple I2C devices 中说： @calin those who use Grove certainly are. don't know... i never used that one... didn't even attempted...

I can power it through my mobile phone charger or a battery pack, just using a tiny USB3 Adapter; and I can power it off my solar panel. I just like the idea of having a web server (or whatever else I made ...) that I can plug into an AC socket.
