EEPROM Simulator
Cloud · Board: ESP32 · Day 41 of 100
Emulate persistent EEPROM storage in flash on the ESP32. Save settings across reboots the embedded way.
How it works
Settings are packed into a reserved region of the ESP32's flash memory and rewritten whenever they change, surviving power cycles just like real EEPROM. Reads are instant from flash; writes are batched to respect the flash's limited write endurance.
What you'll learn
- Flash wear leveling
- Persistent configuration
- Write endurance limits
- Key-value storage on MCU
