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.
- Official Espressif header tables list these J1 and J3 signals.
- MTMS, MTDI, GPIO8, GPIO9, and GPIO15 are strapping pins.
- GPIO12 and GPIO13 carry native USB D- and D+.
