With dual-core Xtensa LX7 running at 240MHz, 8MB flash, 512KB SRAM, WiFi 802.11 b/g/n, and Bluetooth LE 5.0, it packs serious IoT capability into a tiny 45×18mm board. Unlike other ESP32-S3 boards, the Nano ESP32 operates at 3.3V logic level and runs both Arduino IDE and MicroPython out of the box. It includes a USB-C connector with HID support for keyboard/mouse emulation, 14 digital I/O pins, 8 analog inputs, and is fully compatible with Arduino IoT Cloud for remote monitoring and control. The board is designed for embedded IoT projects where WiFi connectivity and compact size are essential — from environmental sensors to connected displays to smart home controllers. Its castellated pins allow direct soldering onto custom PCBs for production use. ## Where to Buy - [Arduino Store (US)](https://openhardware.directory/r?to=https%3A%2F%2Fstore-usa.arduino.cc%2Fproducts%2Fnano-esp32&ref=openhardware.directory&product=arduino-nano-esp32&source=md-export) — $18.50 - [Arduino Store (EU)](https://openhardware.directory/r?to=https%3A%2F%2Fstore.arduino.cc%2Fproducts%2Fnano-esp32&ref=openhardware.directory&product=arduino-nano-esp32&source=md-export) — €20.40 - [DigiKey](https://openhardware.directory/r?to=https%3A%2F%2Fwww.digikey.com%2Fen%2Fproducts%2Fdetail%2Farduino%2FABX00092%2F20371542&ref=openhardware.directory&product=arduino-nano-esp32&source=md-export) — $20.00 - [Mouser](https://openhardware.directory/r?to=https%3A%2F%2Fwww.mouser.com%2FProductDetail%2FArduino%2FABX00092&ref=openhardware.directory&product=arduino-nano-esp32&source=md-export) — $20.00 - [Amazon US](https://openhardware.directory/r?to=https%3A%2F%2Fwww.amazon.com%2Fdp%2FB0C947BHK5&ref=openhardware.directory&product=arduino-nano-esp32&source=md-export) — $20.00 - [SparkFun](https://openhardware.directory/r?to=https%3A%2F%2Fwww.sparkfun.com%2Farduino-nano-esp32.html&ref=openhardware.directory&product=arduino-nano-esp32&source=md-export) — $20.00 - [The Pi Hut (UK)](https://openhardware.directory/r?to=https%3A%2F%2Fthepihut.com%2Fproducts%2Farduino-nano-esp32&ref=openhardware.directory&product=arduino-nano-esp32&source=md-export) — £16.50 ## Resources - [product](https://openhardware.directory/r?to=https%3A%2F%2Fstore.arduino.cc%2Fproducts%2Fnano-esp32&ref=openhardware.directory&product=arduino-nano-esp32&source=md-export) - [wiki](https://openhardware.directory/r?to=https%3A%2F%2Fdocs.arduino.cc%2Fhardware%2Fnano-esp32%2F&ref=openhardware.directory&product=arduino-nano-esp32&source=md-export) - [datasheet](https://openhardware.directory/r?to=https%3A%2F%2Fdocs.arduino.cc%2Fresources%2Fdatasheets%2FABX00092-datasheet.pdf&ref=openhardware.directory&product=arduino-nano-esp32&source=md-export) - [schematics](https://openhardware.directory/r?to=https%3A%2F%2Fdocs.arduino.cc%2Fresources%2Fschematics%2FABX00092-schematics.pdf&ref=openhardware.directory&product=arduino-nano-esp32&source=md-export) ## Tags `arduino`, `nano`, `esp32-s3`, `wifi`, `ble`, `iot`, `micropython`, `usb-c` ## Images ![Arduino Nano ESP32](https://nbg1.your-objectstorage.com/openhardware-directory/entities/arduino-nano-esp32/9b0be82f9700.jpg) ![Arduino Nano ESP32](https://nbg1.your-objectstorage.com/openhardware-directory/entities/arduino-nano-esp32/1c30dba2a8f9.jpg) ![Arduino Nano ESP32](https://nbg1.your-objectstorage.com/openhardware-directory/entities/arduino-nano-esp32/0e6c5a94c523.jpg) --- [View full device page](https://openhardware.directory/devices/arduino-nano-esp32)
