This is the one i have on now. https://www.mouser.com/ProductDetail/Winbond/W25Q32JVSSIM-TR?qs=sGAEpiMZZMtI%252BQ06EiAoG4%252BhDIVn9lGK5OuwFBfb0CE%3D

- Sun Mar 10, 2019 5:34 am #81002 Sounds good. You should be able to go up to a 25Q128 (16MByte) chip without problems. That would be useful in applications where you want a large SPIFFs space for holding files. The operational program space is limited to 1MByte so even with OTA updates then 2MByte is sufficient leaving 14 Mbyte for SPIFFs.

- Tue Mar 19, 2019 8:24 am #81206 The ESP8266 can address (for code execution) one 1 Mbyte at a time (8 Mbits). If you want to use more, you must either use something like rboot where you can store up to four images in four slots and only one runs, with that you could use up to 4 Mbyte (32 Mbits). You can use even more (64, 128 Mbits) if you access the memory beyond 1 Mbyte directly, e.g. for a file system or other data. No code.
