Maybe, so I can apply 5V to the chip.... I am going to ask the factory and we will get a answer.

My gut feel from years of experience is they are playing a fast one, the SPI flash would need to be driven also from that regulator, and I sure its not.

Stay tuned.

Why 5? Why not 100? Or 1000? The main point of the power supply regulation requirement is so that you can't overdrive the RF amplifier and boost the transmit power.

- Fri Jan 16, 2015 5:03 pm #7469 Transmission 1MBytes per second (TCP) and screening (cover-up) sheet aluminum transmitter module.
The module is plugged into a 3.3V regulator
Measurement chain 5V via a resistor of 1 ohm.
The control program of the transmitter causes overheating of the chip ESP8266ex?
Power dissipation ESP8266> 1W (5x5 mm)?

- Fri Feb 13, 2015 9:40 am #9651 Fcc requires the module to have the FCC ID printed on top of the module. Did anyone here get a correctly labeled esp12 yet?

I am actually thinking of using the esp12 in a wearable product. The FCC certification for the esp12 is unfortunately excludes portable devices (i.e. It has to be operated at least 20cm from the human body). Does anyone know how the required SAR testing looks like and how expensive this can be?

- Thu Feb 26, 2015 11:38 pm #10853 Hi, found this information about Certification
The chip by it self is certified.
It seems ESP8266-06, -07, -08, and -12 modules (the ones with metal shield) could potentially pass certification
