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 MKR WiFi 1010 documentationOfficial- Standard Arduino MKR form factor; SAMD21G18 ports from the official Arduino pinout PDF.
- GPIO is 3.3 V only and is not 5 V tolerant; max 7 mA per pin.
- A0 (PA02) is a true DAC output. NINA-W102 Wi-Fi/BLE module is internal (not on headers).
- Left header positions 1-14, right header positions 15-28.
