I've not yet got into the GPIO pins. Can someone help me understand how they work? Are some of them special in some way? Do certain pins produce certain polarities or is that software defined? What Voltage do they run on? Sorry for my ignorance and thank you for your time.
Edit: Ok, looking at the RPF docs was quite enlightening. However after the answer and some info in the docs, I have additional questions.
- What is the amp output on the GPIO pins?
- Does 3V3 on the RPF docs mean 3.3V or something else?
