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.

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?
