If I want to connect Seeed Studio XIAO ESP32S3 Sense to this extension screen, will there be a conflict with two TF card slots?

If you connect XIAO ESP32S3 Sense with this extension screen, the data transmission of the TF card will be applied in the Seeed Studio XIAO ESP32S3 Sense. Meanwhile, the TF card on the screen will not be used.

    Hi. I receiver this display with XIAO SMD21 and followed the recommended settings and library downloads, the Seed Studio RoundDisplay, etc. on the Seed Studio wiki for this display. I ended up not making them work and worst, I now have conflicts with the tft_eSPI library that says that there are two different libraries. Any help is appreciated.

    The Round Display is very exciting and has much potential. the display is built well and performs as advertised. Documentation is always improvable but following the instructions and provided example, "Seeed_Arduino_RoundDisplay/examples/TFT_eSPI_Clock
    /TFT_eSPI_Clock.ino" did not quite work. After much research and other examples the answer became known. The two inits, Wire.begin();
    rtc.begin(); should have been placed at the beginning of the Arduino "setup" section. After moving the two inits the example worked perfectly.
    Is it possible to sell or encourage someone to sell a cover/container for the watch, so it can be worn on a hand? I saw one that was created but I have no way to make it.
