Simplified technical illustration. Pin data is source-backed; verify against the linked documentation before wiring.
Hover, tap, or focus a pad to inspect a pin. Use arrow keys to move between pins.
Mapped source · Arduino Nano ESP32 documentationOfficial- Standard Arduino Nano form factor on a u-blox NORA-W106 (ESP32-S3) module; GPIO from the official Arduino full-pinout PDF.
- GPIO is 3.3 V only and is not 5 V tolerant.
- Arduino pin labels differ from raw ESP32-S3 GPIO; aliases give the GPIO. RGB LED on GPIO46/0/45; LED_BUILTIN on GPIO48.
- Left header positions 1-15, right header positions 16-30.
