ESP-07: what do the SMD parts on the "official" adapter do?

Hi,

there is some kind of "official" adapter for the ESP-07 to get it to fit into a breadboard (white PCB). On this adapter, there are three SMD parts (resistors?).

Can you please tell me what those parts are and what they do? I'm planning to create a circuit without the adapter and am concerned I may be missing something when not using those elements.

Thanks in advance

I can't tell you, but I do know that break-out-boards often have low-drop 5 to 3.3V converters on them, so you can power them with 5V (which is bad, imho). Then probably one of them is LDO and the other two are capacitors.

Or can't they be led's + resistors?

Thanks for your answer!

The adapter is much less complex, please see the attached picture:

There is neither an integrated LDO, nor are there additional LEDs on the board (or do you mean the 'integrated' blue and red ones on the ESP-07?)
