Arduino Nano 33 BLE Sense Rev2 questions
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).
How much does the Arduino Nano 33 BLE Sense Rev2 cost?
From $38.7 at Arduino Store (USA). Prices are observed unit prices before tax and shipping.
What are the Arduino Nano 33 BLE Sense Rev2 dimensions?
43.16 × 17.76 mm. A STEP model is available for enclosure fit checks.
