Description
The Arduino Nano ESP32 brings the power of the ESP32-S3 microcontroller to the classic, compact Nano form factor. Designed for flexible prototyping, it supports both the Arduino ecosystem and MicroPython alongside native Wi-Fi and Bluetooth connectivity. It is well-suited for students, hobbyists, and makers building connected IoT devices and embedded applications.
Dual programming and cloud support
Users can seamlessly switch between Arduino programming and MicroPython to best suit their project needs. The board is also compatible with the Arduino IoT Cloud, enabling remote monitoring and secure device control with minimal setup.
Wireless connectivity and processing power
Driven by the u-blox NORA-W106 (ESP32-S3) running at up to 240 MHz, the board includes integrated Wi-Fi and Bluetooth communication. It is equipped with 512 kB SRAM and 16 MB of external flash memory for handling data-intensive wireless tasks.
Compact footprint and USB HID support
Measuring just 18 mm by 45 mm, the tiny footprint makes it easy to integrate into standalone projects and tight enclosures. Its USB-C interface supports HID emulation, allowing the board to act directly as a keyboard or mouse.
