Is there a way to determine what the correct "flash" size to use when building a project is? I've been reading the Espressif V2.0 NONOS SDK documentation and it states that the flash size should be set to 8 mb? How can I do this if the device itself does not have that much flash memory? Or does it? I don't know how to tell.

I have an Electrodragon NodeMCU device.

Thanks.

Use esptool.py to find the flash_id numbers and then Google:
esptool.py -p com3: -b 115200 flash_id
esptool.py V1.1
Connecting...
Manufacturer: e0
Devce: 4016

Which equals a WinBond 32 Mbit Serial memory (4 mb storage).
