Features

• Embedded HTTP web server on the ESP32.
• Onboard LED control (GPIO 2) from the browser.
• Wi-Fi telemetry (RSSI in dBm and percentage) and uptime.
• Real-time reading of the capacitive touch sensor (GPIO 4).
• Free memory and internal chip temperature monitor.
• Nearby Wi-Fi network scanner, with encryption type and signal.
• Automatic Access Point mode when no network is configured.
• Companion Python dashboard to monitor the board from the PC.

Stack

• C++ (Arduino framework) with PlatformIO
• ESP32
• HTML, CSS and JavaScript for the dashboard
• Python
