I took a closer look and compared M5StampS3A vs M5StampS3 BAT and I must say that it is not possible to do any piggyback for pin mapping at the M5StampS3A level since ESP32-S3FN8 vs ESP32-S3-PICO-1-N8R8 have differences in the number of GPIOs (6 pins error), see the difference table below:

So it only remains for M5Stack team to upgrade M5StampS3A for 2/8 PSRAM, i.e. have M5StampS3B version.

In addition, the following screen snippet shows two possible suggestions how the 2x9@2.54mm pins can be assigned.

@teastain can you please share the scheme how to built a MOSFET inside a M5Stack Proto Unit. Thanks

Hello @magister

in the mean time you could try and copy the correct Python statement into an Execute mpy code block. You can find it under System.

Thanks

@ajb2k3 I'm not so sure. It is a fairly large request, and probably needs funding. It needs to be initiated by the suppliers, only then it will be directed to the micropython writers.

@Maethaxi Thanks I was looking for a Tube/Air Pressure unit with a I2C interface... I was trying to use the M5Stack Tube/Air Pressure Unit but I am running into an issue so I figured I would look for other options if I can't get it to work accurately... I need a sensor sensitive enough to detect someone blowing lightly in a tube....
