Hi Ben

Would it be possible to add an ESP32s3 mini-1 as a target?
It has more pins.

Current selection from FC11 ESP32s3 mini does not have all the necessary ports and pins:

Hi Ben

Perfect!

I was able to connect all the pins and it works in the simulation.
I will test it with the hardware soon.

Hi Ben

One more question.
The ESP32S3 Mini has 3 UARTs.
Can you add the third one?

Hi Ben

Here's another small issue
For me, the most important thing is that UART0 is mapped to GPIO 43 (TX) and GPIO 44 (RX).

Maybe it's just a graphics issue with the PIN number:
