About ESPConnect
ESPConnect is a browser-based tool for managing ESP32 and ESP8266 boards. It allows users to inspect hardware details, manage file systems, back up flash memory, and deploy firmware without installing additional software. The application runs entirely within a Chromium-based browser, requiring only a USB connection to the device.
It supports various ESP32 models and the ESP8266, though with limited functionality for the latter. The tool provides features like file system management, partition inspection, firmware flashing, and serial monitoring. Users can access it directly from a web browser or run it locally via Electron or Docker.
