The NEW ESP32-S3, Artificial Intelligence, more power, more pins, more everything - Nearly!

[@markday3145]

From the block diagram, there appears to be integrated USB OTG (like the ESP32-S2), with JTAG over USB. I like the built-in support for USB. I also see separate blocks for LED and motor control PWM, and a pulse counter; this suggests better support for controlling motors. The ultra low power coprocessor is probably the upgraded one from the ESP32-S2. Sounds very interesting.

[@XTronical]

Yes, speculation is some good features from s2 have carried over. Hopefully see some in the wild soon.

[@randomname3894]

Would be awesome to ditch the serial chip and transistors for usb in future designs!

I would love to see lower power usage during Bluetooth LE sleep. The old ESP32 was about 100 times less energy efficient for Bluetooth LE advertisements than some of the Nordic Semi and TI offerings.

[@paulvandenbossche]

All nice, even SUPER !, but where to buy and at what price ?

[@XTronical]

Availability is poor. Full production hopefully ramped up soon.

[@phillipneal8194]

Wow ! This looks really cool !!!

[@rolyantrauts2304]

The microcontroller 'avx' instructions with the new lx7 core is going to be really interesting for KWS mics. @XTronical you got anything in the pipe line and also wonder if they have done anything with the ADC?

[@XTronical]

At the moment my top priority is to complete my new i2s sound library. Which has been promised for about a year! But yes, I want to give one of these a spin.

[@rolyantrauts2304]

@@XTronical Hopefully they will reconsider the 'blackbox' esp32-who & esp32-skainet libs and change to supporting a more general tensorflow4microntrollers approach than restrictive commercial interest of selling software solution on their hardware

[@phillipneal8194]

With better PWM and Counters it looks like it was built for autonomous robot cars....

[@XTronical]

Certainly has a lot of potential

Would have loved to see 5Ghz wifi

I have been following you recently, as I have recently been using esp32 ... your videos are very interesting and have helped me a lot in solving many problems ... but only a tutorial on a very ambitious project I have not found among your videos. .. the espnow methodologists .. let two esp32 talk via wifi ... or better turn on a led connected to an esp32 through a button connected to another esp32 and vice versa .... !!!! PS: if you want I can pass you the sketch, I managed to make them work via espnow Davide

[@XTronical]

Your right, I've not done anything like this.

[@davyponte]

@@XTronical I suggest you do a tutorial on espnow ... I only found a web page on the net. the project was not basic (led and button) but more complex ... after changing many commands and changing the original sketch. I managed to get it all working.

[@TheOldKid]

Still haven't found anyone that knows what wroom and wrover stand for

[@XTronical]

Beats me too!

[@poepflater]

OK, take my money!

[@XTronical]

And mine too!

[@WistrelChianti]

Ta. Didn't know about this or that blutooth 5 existed or that there was such a thing as AIoT XD

[@browaruspierogus2182]

Answer: No. Too low sram, too low op/s, only 32bit, too low SPI clocks, not fully open sdk. Better check out Kendryte K210

[@ridvanffm]

I like K210, but its community and docs are still emerging.
