I have just run in this blog message from Scott Shawcroft. He explains that in 2021 they will probably spend some time to try to create a port of CircuitPython for ESP32-S3 and maybe also a port for ESP32.

I'm crossing my finger hoping to see CircuitPython support for ESP32!!

In my point of view it would be great to have an M5 core with the ESP32-S2.
The S2 variant has the USB-OTG, and with the right bootloader (TinyUF2 Bootloader), it can expose the internal flash as a USB drive. No more AMPY or custom tools to updload files on the core. We would be able to use the Mu editor on the same easy way as we can do with the Micro:bit.

Last but not least, there is already a port of Adafruit CircuitPython for the ESP32-S2. CircuitPython is very well documented with tons of library alredy written for it.
I find easier to work with CircuitPython than MicroPython.

Let's look for example how CircuitPython handle the audio:

• It use the same libraries regardless of the porting
• It has support for reading MP3 files
• You can choose to use a PWM or an I2S output
• There are plenty of examples

If you need to PWM the output, you can use a mosfet module. You can find a cheap one on eBay or AliExpress.

Yes, it will work with the PbHUB.
This is an example on UI Flow. The relay is connected to PbHUB port 0

The following example is this expression:
(var1 > 50 and var1 < 70) and (var2 > 10 and var2 < 20) and (var3 > 30 or var4 > 50)

Step 4

In UIFlow for Core2 under MediaTrans there are Mir Record and Audio Play sections with serveral blocks. I tried to search a little bit but I wasn't able to find any documentation on these blocks. Can you please point me to the documentation if already exist or else give me some information about these blocks?

I have moved this request in the new Feature Wish List channel.
If you, like me, desire to have this feature, please upvote the post new post.

I propose to add Speaker.beep, Speaker.volume and play tone blocks also to Core2

@mathias can you please write the logic expression that you want to code in UIFlow?

Example:
(var1 > 50 and var1 < 70) and (var2 > 10 and var2 < 20) and (var3 > 30 or var4 > 50)

I don't exactly know what you would like to do, but you can do something like this:
