3. The modular transmitter must have its own power supply regulation
Note: power supply regulation has been integrated in “chip ESP8266”.

They state, however this is not true, and hence the approval is bogus and will be denied.

This would mean I can put 5V or maybe 6V on the chip and it will regulate to its 3.3V, which we all know is clearly NOT the case.

Really annoying why they just did not add a regulator!

Anyway you;ll see this is a short lived approval.

Good spot! That could have bitten us if we relied on it later on!!

- Fri Jan 09, 2015 3:49 pm #6838 Maybe it gets downgraded to limited modular certification and the power supply of the host has to meet a minimum spec which it almost certainly would anyway for proper operation.

Also there are plenty of modular certified products with on-chip regulation (no separate regulator) and that does not mean they have to support a wide range of input voltages. We don't really know what on-chip regulation there is in ESP8266.

I don't think so. SOC core probably works at 1.xV like in ARM chips.
