Arduino Nano ESP32 — ESP32-S3 Dual-Core 240 MHz — Wi-Fi & Bluetooth 5.0 — Arduino & MicroPython
The Arduino Nano ESP32 squeezes the ESP32-S3 dual-core Xtensa LX7 processor into the classic 45 × 18 mm Nano footprint — bringing 240 MHz of compute, 16 MB of flash, and native Wi-Fi plus Bluetooth 5.0 to every project without adding bulk. Fully programmable in both Arduino IDE and MicroPython, it's the most capable Nano ever made, ready for beginners and professionals alike.
Key Highlights
- ESP32-S3 Dual-Core at 240 MHz — Two Xtensa LX7 cores running up to 240 MHz give you true parallel processing for sensor fusion, wireless communication, and real-time control — all at once, without compromise.
- Wi-Fi & Bluetooth 5.0 Built In — The u-blox NORA-W106 module delivers 2.4 GHz Wi-Fi and Bluetooth Low Energy 5.0 with an onboard antenna, eliminating the need for external wireless shields entirely.
- Dual-Language Programming — Switch fluidly between Arduino IDE and MicroPython without changing boards or bootloaders — one board covers both ecosystems, accelerating prototyping and teaching.
- Arduino IoT Cloud Ready — Connect to the Arduino IoT Cloud in minutes to create live dashboards, automate triggers, and monitor your project remotely from any browser or the official mobile app.
- USB-C with HID Emulation — The USB-C port handles programming, serial communication, and full Human Interface Device emulation — build custom keyboards, mice, and gamepads with no additional hardware.
- 16 MB Flash + 8 MB PSRAM — Abundant memory lets you store large MicroPython environments, web server assets, machine-learning models, or extended sensor logs directly on the board.
- All-Digital-Pin Interrupts — Every digital I/O pin supports external interrupts, giving you maximum flexibility for responsive, event-driven designs without rewiring around a fixed interrupt map.
- Built-In RGB + Status LED — An onboard RGB LED (pins 14–16) and a single LED (pin 13) let you visualise connectivity state, sensor alerts, or custom animations with zero extra components.

Frequently Asked Questions
What programming environments are compatible with the Arduino Nano ESP32?
The Nano ESP32 is fully compatible with the Arduino IDE (version 2.x and above) using the official Arduino ESP32 board package. It also runs MicroPython natively, accessible via any serial terminal with the built-in REPL over USB-C. For cloud-connected projects, the Arduino IoT Cloud dashboard works out of the box through the Arduino IDE integration. No third-party toolchains or vendor SDKs are required for either environment.
How do I power the Arduino Nano ESP32?
The easiest option is the USB-C port, which accepts up to 5 V and powers the board directly during programming and standalone operation. For battery or wall-adapter projects, the VIN pin accepts 6–21 V, regulated internally to 3.3 V for the logic rail. All I/O pins operate at 3.3 V — never connect 5 V signals directly to the GPIO without a level shifter. The board does not include a LiPo charging circuit, so a dedicated charging shield is needed for battery-powered builds.
What operating systems and firmware does the Nano ESP32 support?
The Arduino IDE and the required ESP32 board package run on Windows, macOS, and Linux without any additional driver installation on modern systems. The board ships with an Arduino bootloader pre-flashed, making it immediately recognisable by the IDE on plug-in. For MicroPython users, the official MicroPython ESP32-S3 firmware can be flashed using esptool.py, also cross-platform. Firmware updates and board package releases are managed through Arduino's Boards Manager or the MicroPython project's release page.
Does the Nano ESP32 have onboard or expandable storage?
Yes — the board includes 16 MB of external QSPI flash soldered directly to the module, which stores your sketch or MicroPython scripts, filesystem assets, and configuration data. There is no SD card slot on the board itself, but any SPI-connected SD module will work using the SPI pins (D11/D12/D13) with any free GPIO as Chip Select. The 8 MB PSRAM is available for dynamic memory allocation, making it suitable for buffering large data structures or ML model weights entirely in RAM.
What accessories do I need to start building with the Nano ESP32?
At minimum, you need a USB-C cable (data-capable, not charge-only) and a computer with the Arduino IDE or MicroPython tooling installed — the board is otherwise self-contained for Wi-Fi and Bluetooth projects. A solderless breadboard and some jumper wires make sensor and actuator prototyping much easier. If you plan to run the board standalone without a laptop, a 5 V USB power bank or a 6–21 V wall adapter connected to the VIN pin is all you need. The header version (ABX00083 with headers) plugs directly into a breadboard with no soldering.
How does the Nano ESP32 compare to the Arduino Nano 33 IoT?
The Nano ESP32 is a significant step up from the Nano 33 IoT, which used a SAMD21 processor running at 48 MHz with just 256 KB of flash and 32 KB of RAM. The Nano ESP32 replaces this with a 240 MHz dual-core ESP32-S3, 16 MB of flash, and 8 MB of PSRAM — dramatically expanding what's possible in the same footprint. Bluetooth 5.0 LE replaces the older BLE 4.2 of the 33 IoT, and the addition of MicroPython support and USB HID emulation are exclusive to the Nano ESP32. Both boards share the same Nano form factor, so many existing shields are physically compatible.
How many GPIO and communication interfaces does the Nano ESP32 provide?
The board exposes 14 digital I/O pins, all of which support external interrupts, and 8 analog input pins with 12-bit ADC resolution. For serial communication, you get 2× UART, 1× I2C (A4/SDA, A5/SCL for Nano shield compatibility), and 1× SPI bus (D11/D12/D13 with any GPIO as CS). Five pins support PWM output for motor and LED dimming control. All I/O is 3.3 V logic only — level shifting is required when interfacing with 5 V peripherals.
Is the Arduino Nano ESP32 suitable for beginners?
Yes — the Nano ESP32 is one of the most beginner-accessible wireless boards Arduino has released, because it works identically to any other Nano in the Arduino IDE with the same pin naming convention beginners already know. The extensive Arduino documentation, built-in example sketches, and the visual Arduino IoT Cloud interface all lower the barrier to a first connected project significantly. For students coming from Python backgrounds, MicroPython with a REPL console removes the need to understand compiled code at all. Advanced users are equally well served by the raw power of the ESP32-S3 and the complete ESP-IDF compatibility underneath.
What is the most common mistake users make with the Nano ESP32?
The single most frequent issue is connecting 5 V peripherals directly to the GPIO pins, which are rated for 3.3 V only — this can permanently damage the ESP32-S3 chip. A related mistake is powering the board through the USB-C port with a charger that exceeds 5 V; only the VIN pin is designed for higher voltages up to 21 V. Some users also select the wrong board in the Arduino IDE after installing the ESP32 package, choosing a generic ESP32-S3 target instead of the Arduino Nano ESP32 entry, which can cause pin mapping errors and broken LED assignments.
Where can I find documentation, firmware updates, and community support?
The official Arduino documentation hub at docs.arduino.cc/hardware/nano-esp32 is the primary source for pinout diagrams, cheat sheets, getting-started guides, and the full datasheet (ABX00083). Board package updates are delivered automatically through the Arduino IDE Boards Manager by keeping the Arduino ESP32 package current. The Arduino Forum and the official Arduino Discord server host active communities where both beginners and experienced developers share projects, troubleshoot issues, and post library recommendations. For MicroPython-specific resources, the micropython.org documentation and the MicroPython GitHub repository provide firmware releases and API references.
