@bernie have you programmed it before?
It is certainly do-able, but requires that you have the installed program that is currently running, then modify it, I.e. with Arduino IDE and add the functionality that you want.
Are you using Arduino IDE v2.1.0?
If so, I consider this a confusing and annoying bug in the application.
The app kindly and incorrectly identifies your board type!
You still need to type in ESP32S3 Dev Module as shown below on my computer!
@ivan Hi Ivan, this site is a volunteer user community site and anything I say is simply "advice".
LilyGO make no claim of waterproof, but it seems well sealed.
I think accidental splashing such as washing hands would be OK.
Otherwise I would "Damp-Cloth" it as you say!
Great news! Thanks to the efforts of @kreier, a USB VID/PID was able to be secured using a third-party so that official circuitpython support could be added. The T-Display RP2040 now has official CircuitPython support! 🥳
