Arduino has certainly been busy lately. After releasing the Arduino Giga at the beginning of the year, they followed up by releasing two new Arduino Uno boards. And, as if that wasn’t enough, they have just added another member to the growing Arduino Nano family – the Arduino Nano ESP32.

Although a few of the Nano boards already have ESP32 chips, those boards use the ESP32 as a communications coprocessor. This new Nano is the first Arduino board to use the ESP32 as its main processor.

We will begin by looking at the board features and pinouts. Of course, all Nano boards use the same pinout, allowing you to repurpose any prototyping tools you have gathered for the other family members.

At the heart of the board is an ESP32-S3 module, so the new Nano board has essentially the same specifications as other boards built around that chip.

We’ll also use the board with MicroPython, and I’ll show you how to install the MicroPython bootloader. Don’t worry; you can revert to C++ by reinstalling the Arduino Bootloader. I’ll show you how to do that as well.

And we will build a project for the Arduino IoT Cloud. The Arduino Nano ESP32 is an inexpensive way of creating IoT applications.
