ESP32 Forum

Hi,

I read from documents that ESP32 should have at least around 4 MB of flash memory. However, after I compile codes in Arduino IDE, it says that my "program storage space" is only around 1.3 MB. I wonder if this is a normal situation.

I would also like to ask if it is possible to use more flash memory storage in Arduino IDE.

Thank you very much for your help.

The maximum sketch size is determined by your partition scheme. If you choose a larger partition scheme, you can upload larger sketches.
Note that some boards in the list may not have these set properly, the "dev module" boards do.

Thank you for your reply. Could you let me know how to modify the partition scheme?
