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.

Hi everyone - It's come to my attention that there has been someone masquerading as myself, responding to some comments here with a link to a Telegram chat to win a prize from me. THIS IS A SCAM, I am not holding a contest, nor do I have a Telegram account. PLEASE DO NOT RESPOND TO THESE MESSAGES!! It's happening on a lot of my videos, I'm taking steps to remove them manually, but as I have 162 videos, it will take some time. If you do run across a suspicious comment, I would appreciate you letting me know at info@dronebotworkshop.com/ Thanks! Bill (The real one!)

This video is a fundraiser for the Hawai‘i Community Foundation's "Maui Strong: Fire Relief Fund" to help provide support for the people in Maui who lost so much. I lived in Hawaii for almost a decade and although I lived in Honolulu, Maui was always my favorite island, and Lahaina was my favorite place. To see it demolished so quickly, and all that loss of life, is just devastating. If you are able to, please consider making a donation. Mahalo!

After trying to get a project working with the memory limitations of a nano, I bought one of these after watching this video. I’ve been missing out with all the extra features described here! Once again, excellent video!
-
Thanks for a great video, Bill. I've spent quite a bit of time on W. Maul. My parent's condo in Honokawai was spared, but still without power. Condolences to those who lost loved ones and property in Lahaina. Hoping the banyan tree recovers. Big decisions now, for residents and city planners for how to proceed.

I've been wanting to get back into Arduino tinkering (I bult a few projects in the early 10's), but I had been put off by the "curve to entry" as I'll call it. Getting all the things setup and talking and whatnot. Well your video has it all! Basic setup, advanced setup (MicroPython), how to do it, undo it, get started again, all the way through communicating with the Arduino cloud - what a brilliant tutorial!
-
Fantastic video! Great content in a very approachable format for both new and seasoned electronics enthusiasts! Thank you!!!
-
Best tutorial ever. You covered all the new features and comparsion with all other previous boards. Just placed an order. Greetings from Toronto.
-
Excellent video! Very high quality production. Thanks!
-
Great ! I always support using newer hardware which allows implement more advanced projects. I enjoy using ESP32S3 in my projects!
-
I love the way you explain things. They are much more detailed than others. Thanks
-
It is plesure to see your new videos. You are the best.
-
Great video ! As always, it clear and easy to get in touch with devices you talk about. I am really tempted to buy this little Nano and start experimenting with it. Thanks.
-
Thanks for the video. Very thorough and complete.
-
Thank you Bill for everything you do!!! Total novice here but your video's are inspiring and make me want to dive into things I have only ever imagined. Thank you.
-
Incredibly useful info. Thank you!

😂 Love the bit about the shirt at the start. I sometimes get comments about my shirts at work because I don't work Wednesday or Thursday, so sometimes I wear the same shirt two days in a row as far as other staff see. Gets even worse when I've got 2 of the same shirt and wear what seems to be the same shirt all week.
-
Thanks for the video. I just got one of these.
-
Thank you for another video like nowhere to be found on YT. Your detail in presentation and video editing is unsurpassed. One tip for new Arduino cloud users: Arduino has an offer this fall where you can buy an Arduino ESP32 for $1 (excluding shipping...) ONLY when you upgrade to a yearly plan which also is has a 30% discount.
-
As usual, high quality content.
-
Great and helpful pedagogy as usual. Thank you Sir.
