Own project: a free, interactive pinout reference for the whole ESP32 family.
React & TypeScriptEspressif KiCad dataOpen source
Pick the wrong pin on an ESP32 and the device fails to boot, or crashes as soon as Wi-Fi starts. esp32pin.com shows every pin of more than 20 modules and dev boards with its real-world constraints: strapping pins, flash bus, ADC/Wi-Fi conflicts. The pin data comes straight from Espressif's official KiCad libraries; schematic and module views, a pin-mapping builder and PNG/PDF export included.
