Bolt Wifi Module parts

Can someone please explain all the parts of the wifi module and their functions, I still don’t have a clear understanding of what each port is used for.

Not the name of the module, the function of each pin (3V3, 5V A0, etc)

Follow up the training and you will know everything. Also that way it would have a surprise effect🤣.
