Arduino Nano ESP32 questions
What microcontroller does the Arduino Nano ESP32 use?
The Arduino Nano ESP32 is built around the ESP32-S3R8, alongside NORA-W106-10B, MP2322GQH, GD25B128EWIGR, PRTR5V0U2X,215.
How many GPIO pins does the Arduino Nano ESP32 have?
24 GPIO pins are exposed. Xirkit documents 30 board pins, 25 of them with pin-level electrical limits.
Are the Arduino Nano ESP32 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: 2.475–3.6 V.
How much current can a Arduino Nano ESP32 GPIO pin source?
Documented output-high current per pin: 40 mA typ. Values are traced to the chip datasheet; see the pinout table for per-pin limits and conditions.
What voltage powers the Arduino Nano ESP32?
Supply range 4.8–21 V. Power inputs: VIN (6–21 V).
How much does the Arduino Nano ESP32 cost?
From $19.3 at Arduino Store (USA). Prices are observed unit prices before tax and shipping.
What are the Arduino Nano ESP32 dimensions?
43.18 × 17.78 mm. A STEP model is available for enclosure fit checks.
Which interfaces does the Arduino Nano ESP32 support?
gpio, pwm, spi, led, gpio_matrix, adc, touch, rtc_gpio, i2c, uart, clock, control, usb.
How do I program the Arduino Nano ESP32?
Supported frameworks: Arduino ESP32 core, MicroPython, Arduino Cloud.
Where does this Arduino Nano ESP32 data come from?
Every value in this record is traced to a source — 2 documents including the board and chip datasheets — with the page and table cited per value. Unknowns are left explicit, never guessed.
