There are different levels of "support" for a capability. For example:
- The Arduino company provides an official actively maintained library with comprehensive documentation, making it easy to use the capability in Arduino sketches.
- There is a 3rd party Arduino library that facilitates the use of the capability in Arduino sketches.
- The hardware has the capability, but there isn't an Arduino library to facilitate its use, meaning you must use lower level code.
- The hardware does not have the capability.
When you see a capability listed in the specs of a hardware product, it should generally only be taken as a claim that the hardware has that capability, without implying any specific level of support by the libraries and documentation.
