ESP8266 flash specs


#1

The ESP8266 supports external flash. How much flash is on this ESP8266 board?


#2

The chip has 4 Mbytes of flash.

Neat, thanks. That’s what the datasheet seemed to suggest was built in to the ESP-12, but the sheet also suggested there was a max. of 16Mb possible, and that external flash could be added, so i thought i’d check.
