I don't remember which firmware my M2 is using now. Is it possible to download it from M2? thanks.

Nope, the microcontroller is running compiled code and the Arduino IDE doesn't give you any way to exhume the bits from the Flash ROM.

However, if you check the console / serial log after (re)starting the microcontroller, you'll find Marlin's version information. Not everybody updates the info, though, so it may not be definitive, but at least you can rule out firmware displaying different versions.

Your connection log from when you initially connect should tell you what version of the firmware you are running.
If you need firmware, or are just wanting to check, you can compare at firmware.makergear.com.
