New here, and general newbie. I'm working on the following project:

http://www.instructables.com/id/Control ... /?ALLSTEPS

I bought an Huzzah Esp2866 breakout from adafruit which has some different pins.



Can someone tell me what would be the VCC counterpart on the breakout compared to the original Esp2866 as shown in the instructables link?

Thank you

V+ which looks to be row 8 on the left side of your photo feeds the onboard voltage regulator and can be used as an alternative to 3V. If used it needs 5 or more volts usefull if you don't have a 3.3V supply.
Off hand LDO is a 3.3V supply from the onboard regulator if you use V+, there is a spare 250mA if you need to power something else but I would put 100uF on it if you use it.
