Arduino Nano ESP32

The Arduino Nano ESP32 brings the ESP32-S3 into the familiar Nano form factor, supporting both Arduino and MicroPython programming. Based on the u-blox NORA-W106-10B module, it features Wi-Fi and Bluetooth Low Energy with a built-in antenna, making it ideal for IoT projects.

The board runs a 32-bit Xtensa LX7 dual-core processor at up to 240 MHz, with 512 KB SRAM and 16 MB external flash. It operates at 3.3 V logic and connects via USB-C for programming and power.
