Arduino Nano ESP32 Review - Official ESP32-S3 Board from Arduino

The Nano ESP32 officially brings the ESP32-S3 to the world of Arduino and MicroPython programming. It uses the well-known Arduino Nano form factor and includes Wi-Fi and Bluetooth. I got hold of one and I have been testing it. Here is what I found out.

It's not just a dual core, there is also a third ultra low power core who is working when the two main cores are in deep sleep. It isnt able to access every memory region (which is quite fragmented in this architecture) but in many cases you can use interrupts of the periphery or program some timer to wake up the main cores every now an than. If running on batteries this can extend their lifetime quite a lot

The Nano ESP32 works JUST FINE with Espressif's "esp32" board package. It's the last board in the menu. The one from Arduino is EXACTLY the same, but has only that board in the list. That is it!

Just want give you, and your viewers, a little warning: The pictures of the potentiometer is a little confusing. The one on your board says "B10K". The "B" means that it has a linear track. But the one you show as example connections is marked "A10k". The "A" means that it has a logarithmic track. Using a "A" potentiometer in this case would give a very different result.

Well done, mate. I did buy one for testing in Canada, mostly the shipping issue surfaced. However, you didn't comment about ESP_NOW peer to peer WiFi. I will try it out for sure with ESP32-S3 from Espressif, itself. The tips about getting the correct library and port will save me lots for which I am indebted to you for your video. I will also try Platform IO, too.

Thank you so much for reviewing this awesome board! Please make more videos about it.

Thanks for the introduction to the new Nano. I also like your explanation on MQTT. Just joined your channel.😀

One important point I did not see in the video (sorry if I missed) is that the pins work at 3.3V. So, while the pinout is (nearly) the same in all Nanos, some Nanos (like the original one and the Every) work at 5V while others (like the ESP32 and the BLE) work at 3.3V.

Great video Gary! I sure wish the Arduino Cloud would come out with push notifications.

Thank You for helping make-sense of this ESP32 architecture in the multicore just getting going here five years too late. ;-)

Finally an Arduino board (at least among the non-avr versions) with a pin layout and routing that doesn't burry my OCD deeply underground. Almost all pins of the MCU are exposed (except for 6) and are not completely random. I almost gave up on the new boards (having used the Nano 33 IoT with conflicting documentation), but now I want this in my collection too.

I have many, many, many... OK, 5 ESP32 Feathers in my workbench ready to rock, this is probably different in a number of ways. I'll probably keep them around (and buy updated ones) because I heavily prefer Bluetooth Classic over BLE, but having a Nano board (castellated pads) with USB-C is going to be incredible for adapter board designs.

I got mine in the mail today, but have not tried it out yet. Anyway, I also have a few raspberry pico's, but I find them to be hassle to setup for just programming them, while Arduino feels like a few mouseclicks away.

Before I saw your video, I chose the serial port to do the upload and it worked great. Now I just tried what you said re the DFU port and after an ok upload the sketch fails trying to write to the serial monitor. I then changed tho port back to Serial and the output started. Seems like there may be more to it.

Great review ! What would be the impact if I drive stepper motors with it?

[youssubernfissi]

doesn't it have less pins ? so other than slightly easier programing what benefit would you have choosing this over other s3 boards ?

[RixtronixLAB]

Well done, keep it up, thanks for sharing it with us:)

[mal]

$20!!... no thanks. I'll wait till the price comes down to a more reasonable level...

[viktorhugo]

This seems a good board but a little expensive. Many projects can done with the older and cheaper ESP32. USB support and more GPIO and BLE 5.0 is the Differenz to the old one.

[zeffster]

I love esp32, and if this there is no downside other than price I'm gonna take that hit. Im always looking for alternatives to Chinese things.

[paulstubbs]

Wow, a tad expensive, especially the transport - anyone would think its a 50KG block by the mail charges.
