About ESPConnect

ESPConnect is a browser-based control center for ESP32- and ESP8266-class boards. It runs entirely inside a modern Chromium browser so you can inspect hardware details, manage SPIFFS, Fat, LittleFS files, back up flash, and deploy firmware without installing desktop software. It is based on Jason2866's WebSerial ESPTool. - Tutorial
