I don't believe there is one.

Thank you for the confirmation, Python Coder.
I was intrigued to read above "this requires that you have the tile which contains the tiny buzzer".

Can anybody please explain where can I find a tile with a buzzer?

Hi, friends.
Why don't we have the NeoPixel module builtin on the Pyboard? It's on the ESPs and on the Pyboard D, but not on the v1.1.
How can I put it into the firmware?
Thank you all in advance.

I guess I found it in the data sheet for the SF6W STM32:
https://www.st.com/resource/en/datashee ... f767zi.pdf
Maximum sunk or sourced current per pin: 25mA.
Maximum total output current sunk or sourced by sum of all I/Os and control: 120mA.

Hi, friends. Does anybody know where can I find information about voltage and current ratings for the Pyboard D pins? Any information about sink and source maximum current would be welcome. I wonder if I can connect any load directly (a buzzer, for instance) or if I should use a buffer or a driver. ...

Hi. I know the tile sensa, but you were talking about a 'tiny buzzer'. AFAIK, there is no tile sensa with a buzzer. So, there is no buzzer to be set up by the driver. Am I wrong?

Buzzer on Tile Sensa? I have never heard of it. Where can I find more about this buzzer?

Awesome!

Hi, friends.
Does anybody know of a header, pin connector or something like that for the X and Y positions through-holes?
I know the WBUS-DIP28 and DIP-68, but they are expensive and sometimes are just too much for a simple 3 or 4 pins connection.

Because machine is portable it lacks some hardware-specific features. My approach is to use machine where possible, but be aware that there are some very nice features of the STM boards accessible only via pyb.

Taking lessons from another legend: Peter Hinch. Thank you so much!
