ESP_DoubleResetDetector is a library for the ESP32/ESP8266 Arduino platform to enable trigger configure mode by resetting twice.

Hardware-based authentication using SRAM Physical Unclonable Functions (PUF) on ESP32 microcontrollers. Research-based PoC with 44,778 measurements across 16 devices over 6 months.

An intuitive library to simplify read and write operations on RTC memory of ESP8266 and its backup on flash memory.

Library to detect a multi reset within a predetermined time, using RTC Memory, EEPROM, LittleFS or SPIFFS for ESP8266 and ESP32, ESP32_C3, ESP32_S2, ESP32_S3. An alternative start-up mode can be used. One example use is to allow re-configuration of device WiFi credentials

Low Energy BME280 Sensor using rtc memory and MQTT

🔒 Authenticate devices using ESP32 SRAM PUFs, leveraging unique hardware fingerprints to generate secure tokens without storing credentials.

ESP32 crash blackbox and field diagnostics Arduino library with RTC/NOINIT logging, ESP-NOW heartbeat monitoring, neighbor watchdog, health scoring, boot storm detection, and metric alerts.
