 # 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® as well as Bluetooth® LE.
 
 The Nano ESP32 is compatible with the Arduino Cloud, and has support for MicroPython. It is an ideal board for getting started with IoT development.
