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

- Sat Mar 19, 2016 6:53 am #43540 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.

- Sat Mar 19, 2016 6:54 am #43541 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?)
