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.

DUDE!!! back the camera up. I dont need to be able to count your nose hairs.
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.
Incredibly clear and helpful. Thank you.
great video, very informative
This is great! Exactly the kind of questions I had.
Thanks Mike!
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.
Glad I could help!
nice video sir. have you ever design a product base esp32 to read IEPE sensor sir?
Thank you!
such a useful video thank you
Glad it was helpful!
How cool is this video. Thanks.
Thank you!
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.
Thank you for the feedback and new video suggestion!
good work
Thanks
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..
Great to hear! You can do it!
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.
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?
Depending on your situation you may be able to use the reset button and read the wakeup case to achieve the same effect as wake on touch
great I'm going to get a esp32-c6 to learn about riscv
Helped me understand why ESP is prominent. Typos: "Desing" at 5:46 and 5:51.
Thanks Steve! Darn it, I missed that typo.
Hi, thanks for your video, I am new in IoT domain, I bought Esp32 WROVER, to which family it belongs?
Thanks in advance.
That module uses the older, original ESP32. Thanks for commenting!
@@PredictableDesigns ah ok, thank you for your reply, if I understood, if I need to use Wifi and Bluetooth it's better to go with S3?
@@PredictableDesignsAnd just for information I bought the starter kit from Freenove, do you think that they have their own references for ESP32?
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?
If you don't need WiFi, and only need Bluetooth LE, then I'd go with the H2. There's a lot of overhead to support WiFi so if you don't need it then choose a version without it.
Also, you may want to consider other non-ESP32 chips if only doing BLE, and especially if you need ultra-low current. For example, for BLE only designs I like the nRF52 BLE microcontrollers from Nordic.
The N2, N4, N8,etc at the end of the development kit part number indicates how much memory it has on the dev kit board (Flash and RAM).
I wouldn't be too concerned about the prices of the dev kits since you'll very rarely go to production with those. Instead focus on the cost of the SMT module.
Hope this helps.
@@PredictableDesigns Thanks a lot! This really helps tons... I think I'm going to go for H2 but now what are pros and cons of MINI and WROOM? It would help a lot if you could clarify this!
what would you recomend me if i never use bluettoh or wifi in my projects
That's not quite enough info but I'd probably look at an STM32.
Man this is one of the best videos on TH-cam !
You just made my day! Thank you!!
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?
Yes I can help you inside my Hardware Academy. Cheers.
Seeing your terribly unhappy face on the thumbnail makes me wondering if the poll asking whether to go for the blue or red thumbnail was the right question 😲😂
I would have voted for a more friendly mimmic ^^
That's not my unhappy face, that's my inquisitive face:) I'm rarely unhappy.
So far this video is off to the best start of any video I've done, so I think the thumbnail was a good choice.
@@PredictableDesigns that is not the thumbnail, that is the topic, there is a huge maker community out there using ESP32, you adressed a need
@@rdson1621 Of course I agree, and the ESP32 is a hot topic, but I don't think my expression is hurting the video - but then again it's impossible to know. Nonetheless you did give me the idea to do an A/B test on a thumbnail with a smiling photo vs this one, so thanks. Honestly, I'd prefer to not have my photo on them at all:) I appreciate your feedback!
@@PredictableDesigns I see YTbers more and more adding their face with some mimmic on the thumbnail, especially such ones -> 😳 with hand(s) but I don't understand this trend, for me it doesn't look esthetic. I think it's better no face for our kind of topics.
Well I'm going to also test out thumbnails without photos. If most of my videos weren't closeups of me talking then I would have never included it. But it's worth testing. Thanks again for the feedback!

Oops, not sure how I missed that:)

How rude to call me Teensy:). Haha, just kidding.
