Flash and 1.8V IO
Posted: Sun Nov 15, 2015 11:54 pmAs I understand from the datasheet you can run all of the IO at 1.8V through the VDDPST pins. Can anyone confirm whether that includes the pins used to interface with the external flash? I couldn't find anything specific in the ESP8266EX datasheet but I would assume since the SPI interface can be multiplexed with GPIO that this would be the case.
