Arduino Nano ESP32 (ESP32-S3) Official Development Board
Arduino Nano ESP32 (ESP32-S3) Official Development Board has a 5-10 day lead time before dispatch. Order will only be sent once all items are available for delivery.
The Nano ESP32 brings the ESP32-S3 into the Arduino ecosystem in the compact Nano form factor. It's a solid choice whether you're just starting out with IoT and MicroPython or building the ESP32-S3 into a finished product. Full Arduino IDE support, full MicroPython support, and Wi-Fi® and Bluetooth® connectivity are all built in, so you can go from unboxing to a working prototype fast.
Key Features
- Tiny footprint – the familiar Nano form factor (45 x 18 mm) makes it easy to embed in standalone projects and tight enclosures.
- Wi-Fi® and Bluetooth® – powered by the ESP32-S3 microcontroller, with full Arduino support for wireless and Bluetooth® connectivity.
- Arduino and MicroPython support – switch between Arduino and MicroPython with a few simple steps. See our ESP32 beginner tutorials and ESP32 IoT tutorials to get started.
- Arduino IoT Cloud compatible – build IoT projects in a few lines of code, with security handled for you. Monitor and control your project from anywhere via the Arduino IoT Cloud app.
- HID support – emulate a keyboard or mouse over USB for custom human interface projects.
