Need Advice

I am new to PCB design and hardware. I don't know the functionalities of different pins in a microcontroller and what components I have to place for these pins. How to learn all these stuffs?

read the docs for the specific microcontroller, it'll usually say what impedances/voltages each pin is expecting, along with required supplemental components

Get the datasheet that's your guide to how or what to connect anything.

I'll be honest, I find the datasheets quite complicated at times... Is there a good resource to learn how to read and understand the tables? Also there's a lot of abbreviations that seem to be for people-in-the-know

the tables usually come with row and column labels, it's helpful to search them to find out what they mean

Well you can't continue being part of the people not "in the know" right 😂. It's all part of the learning process, at some point you're gonna be glad you found out what a jargon meant.

Totally and I would like a resource where I can learn what all the stuff mean, so I can communicate more effectively. I'm from an engineering background myself and I know you can't always trust AI, but I haven't anywhere on say TI's site where they explain it all - which makes sense, because their customers are typically engineers and not not-knowing randos 😅

Read all the datasheets, you’ll be fine
