I have a couple of projects comming where I want to operate a wifi device at longer range.
So instead of bodging an aerial onto a esp module that has a pcb one I was thinking of getting a couple of esp modules that have the ufl aerial connector onbaord.
I also see these modules have a 'ceramic' aerial, what are these?, id there a diplexer onboard or is the 'ceramic' doo dah a device that tunes the input or something.
I'm still going to bodge an aerial though, maybe a 3 or 5 element yagi.
