esptool.py --port /dev/ttyUSB0 flash_id

The ID will provide clues about manufacturer and size.


This is what is returned

#60807 not quite.

Mi is short for Megabinary emphasising the difference of 1024*1024 vs. 1000*1000 for the "M" but in IT forums Mi is seldom used, it is more likely for legal aspects in trade (size of hd's)

If you want to show the difference between bits and bytes, some propose to use capital B for Bytes and small b for bits, so it would be 1MB=8Mb
