Product Reference Manual
SKU: ABX00083
Description
The Arduino Nano ESP32 (with and without headers) is a Nano form factor board based on the ESP32-S3
(embedded in the NORA-W106-10B from u-blox®). This is the first Arduino board to be based fully on an ESP32,
and features Wi-Fi®, Bluetooth® LE, debugging via native USB in the Arduino IDE as well as low power.
The Nano ESP32 is compatible with the Arduino IoT Cloud, and has support for MicroPython. It is an ideal board for
getting started with IoT development.
