Answers from the record

Arduino Nano RP2040 Connect pinout FAQ

What microcontroller does the Arduino Nano RP2040 Connect use?

The Arduino Nano RP2040 Connect is built around the RP2040, alongside ESP32-D0WD-V, ATECC608A-MAHDA-T, AT25SF128A-MHB-T, MP2322GQH.

How many GPIO pins does the Arduino Nano RP2040 Connect have?

22 GPIO pins are exposed. Xirkit documents 39 board pins, 28 of them with pin-level electrical limits.

Are the Arduino Nano RP2040 Connect I/O pins 5 V tolerant?

No. The I/O pins are not 5 V tolerant — they run at 3.3 V logic; use a level shifter for 5 V signals. Input-high threshold: 2.31–3.3 V.

How much current can a Arduino Nano RP2040 Connect GPIO pin source?

Documented output-high current per pin: ≤ 8 mA. Values are traced to the chip datasheet; see the pinout table for per-pin limits and conditions.

What voltage powers the Arduino Nano RP2040 Connect?

Supply range 4–20 V. Power inputs: VIN (4–20 V).
