I am just starting to scratch the surface and attempt to understand TTL and serial data ports in general, and am really just trying to put the pieces together and see if I'm on the right path.
First, how do I connect a USB to TTL adapter, such as this one, to my raspberry pi? Do I simply use a USB cable from the pi to this adapter, and then use the pins on the adapter?
Second, will I be able to get readings from a GPS module, such as this one, by wiring it to the TTL adapter?
I ask because I want to attach several devices that require serial data ports to my pi, and as I understand it, the pi only has a single serial data port. So, I'm wondering if my understanding is correct that I can buy these cheap FT232RL USB to TTL adapters and turn my unused USB ports into serial data ports.
