I am new to the Core2 and figuring the nicest way to program it.
Working with flow is nice, but I don't really like the visual programming. I have now switched to Visual Studio Code with the m5stack add-on, it works ok. But as there is code completion, and no documentation on the libraries I now find my self with flow open, dragging components on the sheet and then checking the generated python code.

Where is micropython reference documentation for the Core2?

Core2 power button broken after a few weeks.
Can I claim warranty? Or where can I buy are replacement switch, soldering should not be a problem.
