  For ESP8266 / ESP32 boards

  ESP_WiFiManager_Lite (https://github.com/khoih-prog/ESP_WiFiManager_Lite) is a library 
  for the ESP32/ESP8266 boards to enable store Credentials in EEPROM/SPIFFS/LittleFS for easy 
  configuration/reconfiguration and autoconnect/autoreconnect of WiFi and other services without Hardcoding.
