The ESP32-S3 TFT Feather microcontroller ships running a TFT and NeoPixel demo.
It's lovely, but you probably had other plans for the board. As you start working with
your board, you may want to return to the original code to begin again, or you may

or Arduino. The FTHRS3BOOT drive is part of the UF2 bootloader, and allows you to
drag and drop files, such as CircuitPython. However, on the ESP32-S3 the UF2

Factory Reset Firmware UF2
If you have a bootloader still installed - which means you can double-click to get the F
