ESP32-S3 - Which Pins Are Safe To Use?  @atomic14

I've finished testing the latest boards from PCBWay.com/?from=atomic. One of the problems I found was a conflict with the pins I'd used for the SD Card and the the pins that are needed for PSRAM.

So I thought it would be good to try and collate a bunch of information together on the ESP32-S3 pins.

I've put it all on GitHub here: github.com/atomic14/esp32-s3-pinouts
