It's already being worked on. I personally can't hardly wait to see it. It's going to be an incredibly interesting opportunity to add a bajillion different types of sensors.

Do you know who's working on it? I was thinking of starting too.

[Coopersmith-24601]

M5Stack CoreS3 has AXP2101 power management chip like tbeam-s3-core variant. I managed to start up the CoreS3 with power management.

So, that's it then. It just dies?

Sadness.
