ESP32-CAM: what is the maximum capacity of the microSD card ?

Postby nounours18200 » Sat Feb 29, 2020 10:21 pm

Hi,

I would like to know what is the maximum capacity of the microSD card to remain fully compatible with the ESP-32 CAM specifications: 32 Gb ? more than 32Gb ?

Thank you for your reply,
Nounours

I think it's specified by file system FAT-32

Above 32GB, the card has to be formatted using exFAT filesystem.
exFAT is supported in IDF through FatFS library, but the support is disabled by default. You can try changing #define FF_FS_EXFAT 0 in ffconf.h from 0 to 1, and then rebuild the application.
