Additional Notes
- ESP32-S3 Pins G0 and G46: These are strapping pins that determine the boot mode. By default, G0 is pulled-up and G46 is internally pulled-down, allowing the chip to boot from SPI Flash normally. Avoid pulling G46 high before the chip boots to ensure proper startup. Refer to the Strapping-Pin section of the ESP32-S3 datasheet for more details.
- An SPI interface for a TFT display is reserved on the back of the module. Compatible FPC connector specifications are 8 PIN and 12 PIN.
