I'm building a weather data collector and I want to be able to dump that weather data somewhere. I've considered the options, and since I'm going to be storing a fairly small amount of data (in the megabyte range) I don't want to use SD cards (also SD cards are expensive). I've heard of use of NAND flash memory chips (like the W25Q32), and I was hoping that I could possibly interact with them in a simple way (since most ways require writing to each individual address). Is there possibly a way to build a file system within one of these small flash memory chips and interact with them as simply as interacting with an SD card?

TLDR: I want to interact with a flash memory chip easily to store basic ASCII data

This lib offers a means of reading and writing ASCII arrays to flash devices. This would be a simple solution for such a data logger requirements. It's ASCII orientated.

I don't think you need a file system: that is usually needed when you want to manage many files. Your weather data log sounds like a single file.

What you seem to need is to access EEPROM as a stream, exactly like you would for an open file. There are stream wrappers around some EEPROM libraries, e.g. this one for ESP. I suggest you check it out and see if you can adapt it to the EEPROM library you use.

There is a way to do this. Using a $2 adaptor from eBay, you can hook it up to a micro sd card. An sad card for $4 can store 128mb of data, which is plenty for you.
