Answers from the record

Arduino Nano 33 BLE Sense Rev2 pinout FAQ

What microcontroller does the Arduino Nano 33 BLE Sense Rev2 use?

The Arduino Nano 33 BLE Sense Rev2 is built around the nRF52840-QIAA, alongside NINA-B306, BMI270, BMM150, LPS22HBTR.

How many GPIO pins does the Arduino Nano 33 BLE Sense Rev2 have?

22 GPIO pins are exposed. Xirkit documents 35 board pins, 25 of them with pin-level electrical limits.

Are the Arduino Nano 33 BLE Sense Rev2 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 33 BLE Sense Rev2 GPIO pin source?

Documented output-high current per pin: 1–4 mA. Values are traced to the chip datasheet; see the pinout table for per-pin limits and conditions.

What voltage powers the Arduino Nano 33 BLE Sense Rev2?

Supply range 4.8–21 V. Power inputs: VIN (?–21 V).
