Where can I find the programming abilities of modules?

Forgive my complete lack of knowledge, but I can’t find a knowledge base of things you can program with the various modules. For example, the RAK1904 has capabilities… what are they? i.e. Sample rate, AccelRange? And what do the values represent. I am learning a lot looking at example code, but there must be a place where I can learn about all the capabilities of these devices.

Thanks.

Welcome @paul.carlin in the RAKwireless forum.

The best place to get specs for the modules is our Documentation Center.

Additional information can be found the datasheet of the supplier of the sensor chips.
