M5Stack Atom Echo - Input voltage range - Can I use 12v dc supply?

I’m looking at packaging one of these little badboys in a little assembly which is using a 12v dc supply. Does anyone know what the input voltage range is so I can run the Echo straight from my existing supply?

On a similar topic, can the Bluetooth be used in reverse to have the audio output on another speaker? Or perhaps bodge the pinout to include an aux output?

Any ideas much appreciated!

Did you have a look at the specs or data sheet?

The USB would be 5V of course with ESP needing 3.3v. Peripherals I’m not sure. Maybe 5V?

I would have thought some kind of 12V to 5V convertor would be the way to go, but not sure.
