Which ESP32 is Best for Your Project?

Selecting an ESP32 wireless microcontroller used to be an easy thing to do since there was only one model available.

But, that has all changed in the last few years with the release of multiple new models.

These new models give you more design flexibility, but they make the selection process much more challenging, and in fact quite overwhelming for many.

So, in this video you’re going to learn about the different ESP32 models and how to pick the best one for your project.

Slight clarification: All ESP32s use RISC processors. The difference between the original and S series vs the C and H series is that the former uses processors that are built using Tensilica's Xtensa Instruction Set Architecture (ISA) which is a proprietary RISC ISA that is licensed for manufacture similar to ARM. The C and H series, however, utilize the RISC-V ISA, which is the fifth free and open source RISC ISA to come out of UC-Berkeley. Interestingly, the S3 also includes a RISC-V core for its Ultra-Low-Power mode. Note that the ISA being FOS does not mean that the processor designs are (some are) the licensing for the ISA is rather permissive. However, there are no inherent fees associated with using the ISA in a design, which significantly lowers the cost barrier for custom silicon.

This was the ESP32 refresher I've been looking for. Stepped away from ESP32 a while back and it's good see things are still thriving.

This is really great John! Can you do a video about the software and hardware resources utilized when Wi-Fi and or Bluetooth are turned on and what remaining CPU power and hardware resources are left to your embedded application. This might be more of a software library question.

Thanks a lot for this video! I have been so confused about which board to order. I am a maker, and i love building electronic projects from the internet and customizing them.

Brilliant guide, exactly what I needed to rent myself with the ESP32 series

[programmingelectronics]

This is great! Exactly the kind of questions I had.

Thanks john great video as always. For any hobbyists out there reading this who plan to hand-solder or hot-air their ESP32 module to a custom PCB, I was an idiot and learned too late that if you select the "MINI" version (like an ESP32-S3-MINI-1U), all the pads are underneath the chip and not visible around the outer edge like the non-MINI modules (there's literally a picture on the first page of the datasheet *facepalm*). So hand soldering is kinda out of the question for minis (At least the ESP32-S3-MINI). If you intend to use hot air, you won't be able to visually confirm the melting of the solder paste or if there's any shorts or non-soldered pads (cuz the pads are under the chip and not visible) and it was a problem for me. Your results may vary. So I changed to a non-mini version: ESP32-S3-WROOM-1U

May need to distinguish between generic and specific RISC cores such as LX6/7 and RISC-V. For example, C-series use RISC-V cores, a specific type of RISC processors.

Incredibly clear and helpful. Thank you.

Helped me understand why ESP is prominent. Typos: "Desing" at 5:46 and 5:51.

[rudypieplenbosch]

Thanks for your explanation, i thought about to start some esp hobby project (also need an excuse to buy a scope), but could not determine which version would be usefull, now i can 👍, subscribed.

[stefans]

Thank you John. I believe that the C series also misses the features of capacitive touch and wake on touch that the original ESP32 had? Not sure if that has been deprecated across the range?

[MikeNewham]

Great channel! I look forward to the day to just send a small PCB deign for printing. That would be such an achievement for me..

[dimtim]

what package has the lowest power consumption?

[calvinaizumiramadhan]

nice video sir. have you ever design a product base esp32 to read IEPE sensor sir?

[ze_pixelShot]

Is there any particular advantage in getting an ESP32 C6 instead of H2 and vice versa? I'll be needing no Wifi and only bluetooth, so which one do you recommend? Also between the WROOM and MINI module, which one?

Also I noticed the H2 DevKit is more expensive than C6 DevKit on DigiKey because of low supply, I suppose? So which one can I rely on more when I start mass production?

Edit: Also when you go to order samples -- it says N4, N2 or H4 at the end of the module name -- what is that supposed to mean?

Hi, thanks for your video, I am new in IoT domain, I bought Esp32 WROVER, to which family it belongs?
Thanks in advance.

[venifakumar]

Greetings sir, is esp32 have professional board or it can only used for development

[giusepearturo]

what would you recomend me if i never use bluettoh or wifi in my projects

[nnaemekaizuora]

Good morning Mr John, I wanted to humbly make a request, I am an undergraduate Electrical Engineering student who is currently working on his final year project, would it be possible to hire your services in aiding me with my project?
