Docs?

Just ordered 2 of these modules. Couldn't find much by way of documentation.

Question:

1. What does this line do?
   GPIO.setmode(GPIO.BCM)

2. How do you work with the onboard I2c and UART ?

Many thanks!

See the documentation for the RPi.GPIO python module.
RPi.GPIO was the first Python module for GPIO access.
See e.g. https://sourceforge.net/p/raspberry-gpio-python/wiki/Examples/

For details about i2c and uart see the Raspberry Pi OS documentation on raspberrypi.com
