## AI overview

esp32pin.com is a free, open-source interactive pinout reference for the ESP32 family. It identifies pin constraints such as strapping-pin behavior, ADC2 conflicts with Wi-Fi, flash-pin restrictions, input-only pins, and USB or JTAG warnings.

## Source excerpt

esp32pin.com is a free interactive pinout reference for the ESP32 family. Every pin carries its real-world constraints, the data is generated from Espressif's official KiCad libraries and cross-validated against the esp-gpio-tool dataset, and new dev boards can be proposed right in the browser.
