As a non-EE I'm really curious in what the components at play for the WiFi chip are here!
We have a 37.4kHz crystal.
The orange / white passives are I'm guessing all capacitors with the black ones being resistors. Is the larger passive above the chip a resistor too or perhaps a power supply filter?
The blue passive on the chips antenna output I'm not sure. I see two DC blocking capacitors. Its got a dot so I'm guessing its directional but I don't think its a diode. And I thought Baluns have more pins.
The large white component with the grey square on the waveguide, again not sure. I don't think its a balun, some kind of PI network?
The two green passives on the waveguide, forming part of the matching network I presume, 0-ohm links?
