I want to learn designing IOT PCBs (with 2.4Ghz wireless) (lemmy.ml)

Hi all! I'm a firmware developer with little knowledge in analog electronics.. I deal with firmware for IOT projects all the time.

I had to make a breakout board with an off the shelf RF module with self contained PCB antenna. Now I'm intrigued in the hardware side. I'm inclined to design them from scratch myself. (Obviously ignoring the EMI and FCC certifications for the time being).

What concepts should I be familiar with to achieve this? Starting on I figured to brush up on circuit theory and signals. Where do I go from here? What materials would you recommend? Hopefully I don't need to get into hardcore RF theory to design these PCBs (I know kicad already has these premade antenna blocks).

Thank you.

We never bought a TV because Dad would pick them up at the dump and fix them, doing some sort of magic with the CRTs.

And my grandpa hand-built one of the first radios in the area, and people would come over to listen to radio programs. When phones came to our area, he was running lines on the barbwire fences over to neighbors to use it until the phone coop could get out to hook them up a couple years later.

They were nerds before it was cool. We stand on the shoulders of giants.
