#345 ESP32 vs STM32: Which one is better (Bluepill)?

Many commenters tell me that the STM32 MCUs are great. The last time they were used on this channel was in video #11 on Jul 27, 2015. High time for a closer look.

You always seem to know exactly what I'm wondering about. Thanks so much for the comprehensive comparison.

[jessiegashler]

A genuinely clear and concise comparison of the two. I'll be subscribing to your channel based solely on this video. Fantastic work.

Depending on what you're making, the larger memory of the ESP32 can be a HUUUGE win, probably should have been given a mention in your summary

[RTmadnesstoo]

I always wait a while to watch your videos so the comment section can fill up. Sometimes the comments are almost as good as the video. Almost. Thanks for your efforts.

I personally am using the blackpill for smaller projects. Great video as always! Please more STM32 content 😻👍 (we use them also in our flight controllers ^^)

[Brandon-rcvp]

Thank you for freely sharing such great content. It is intellectually interesting, quirkily entertaining, and best of all technically informative for us trying to get back to our roots in electronics and learn how to operate todays newfangled gadgets :) If I had to guess I would say you are one of those rare individuals that know what an exciter is and at the same time can hold your own at any maker fair today. Good on you sir!

[alfredopreciadomolina]

wow, just what I was looking for, you can't ask for a better explanation, as always, master.

STM32F4xx has FPU, USB OTG working in both, device and host mode (some MCUs have 2 ports), support for external FLASH/SRAM/LCD screen, internal RTC clock, support for SD cards. The debugging capabilities are also awesome - breakpoints, single stepping, memory & register view, SWO tracing. AFAIK, ESP32 can be debugged too :)

that little hand makes me so happy, i giggle every time I see it!

[TheAoab]

Many thanks again for the great efforts to give us comparison results ready and free.

Thank you for this video. I was trying to answer this exact question for the last week. I've been using esp32, but I rarely have any need for internet connectivity. At the moment, I don't think it's worth changing over, but definitely a consideration for future projects. Perfect timing!

[NotMarkKnopfler]

Great video. What I would really like to see is an STM32 video showing how the low power modes work. Particularly wake-on-interrupt. I would really like to see that. Thanks again, Andreas.

[TimSavage-drummer]

The one big advantage I found for the STM32 is the ease at which I can set up a hardware debugger with the STM32Cube IDE. The STM32 Discovery boards are great for prototyping and cheap, I only use ESP boards now for wifi connectivity. Have a black pill driving my DIY modular synth as a MIDI to CV converter, the hardware debugger came in really handy for developing that.

[newburypi]

Yet again, both useful and interesting. Thank you.

[PhG]

Thnxs for this very well explained overview. A nice wrap up !

[mr.meticulous]

Exactly the video I was waiting for! Thanks Andreas :)

Atvantages of stm32: it can act as USB keyboard, serial, even as USB storage... All at the same time if needed.

[shabbarvejlani]

Thank you Sir for your analysis ! Appreciate!

The most kind heart to make this video
