- esp32 EEPROM read/write cycle stack overflow article
\ Summary: \
- ESP32 doesn’t have an actual EEPROM; instead it uses some of its flash storage to mimic an EEPROM
- ESP32 flash goes close to 10,000 cycles
- even automotive grade EEPROM like the 24LC001 which supports at least 1,000,000 writes will only last about 2 months
- EERAM which supports infinite writes and will not loose contents on power loss (microchip 47C04)
