I am searching for a waterproof M5Stack module with battery and IMU. M5Touch could be a solution. But I can't figure out if its possible to add one of the battery modules and if it will fit in the case.

Do you know which of the Battery Bottoms will fit?
Does the IMU Bottom of the Core2 fit?

An alternative solution would be a M5StickC Plus in a waterproof case.

Thanks in advance.

Thanks for the hints. I connected the module and now it works in UIFlow and with your hint in Anduino! Thanks a lot!

I am trying to use GRBL 13.2 module with Core2. But i can't figure out how to set MISO to GPIO38 in UIFlow and Android since it changed from GPIO19.

Without adapting Core2 reboots after calling the library.

Could anyone please gibe me a hint if this is possible and how?

I received my Core2 and GRBL 13.2 module and it works due to @felmue 's hints:
