ESP8266 Community Forum

Hey there,

So I've done something really stupid. I discovered the ESP8266, went around searching for viable IC's to use on a custom board, ordered some units and developed a full breakout board for it. I soldered it all yesterday and I wanted to play with it a little bit so I *began* searching how I could do this.

I've seen a lot of tutorials, tools, github repositories and I was really interested in having FOTA (Firmware Over The Air) but I have no idea if the ESP I bought has the SPI flash required for it. I didn't take into account the possible necessity of having an external SPI flash and now I don't know if the module I bought has it or not. The aliexpress page for the product doesn't mention it and searching the web I can't find it. I bought the ESP8266-12, pictures attached to this post.

Thanks for the help

Howdy,
See the following:

This shows "under the shield" of the ESP-12. It has a 4MBit (512K byte) flash on the board.

It is really depends of the batches...
All my ESP12 have only 512KB but all my ESP12E have 4MB.

Phew, thanks for the clarification ! Time to start playing with some FOTA!
