Microcontroller
Arduino Nano RP2040 Connect
Arduino's Nano-format RP2040 board adds Wi-Fi, Bluetooth, IMU, microphone, and secure element features around Raspberry Pi silicon.
Processor
RP2040 + u-blox NINA-W102
Logic
3.3 V GPIO
Power
Micro-USB, VIN
Format
Nano module
Check before wiring
- GPIO is 3.3 V only and not 5 V tolerant.
- Some RP2040 pins are dedicated to onboard peripherals.
- Use the Arduino pinout for Nano labels rather than a bare RP2040 pin table.

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.
- Standard Arduino Nano form factor; RP2040 GPIO from the official Arduino pinout PDF.
- GPIO is 3.3 V only and is not 5 V tolerant (max GPIO input 3.3 V).
- SDA=A4 (GPIO12), SCL=A5 (GPIO13). A0-A3 are GPIO26-29 (ADC); A6/A7 read via NINA over SPI.
- Left header positions 1-15, right header positions 16-30.

Why it matters
- Useful bridge between RP2040 firmware work and Arduino Cloud examples.
- Official docs cover the Nano labels and board-level peripherals.
- Onboard IMU and microphone reduce external wiring for sensing demos.
