- While holding the button, power on the device.
- After the power is applied, release the G0 button.
Additional Notes
-
ESP32-S3 Pins G0 and G46: These pins are strapping pins that determine the boot mode. By default, G0 is pulled up while G46 is internally pulled down, allowing the chip to boot from SPI Flash normally. Be cautious not to pull G46 high before the chip boots; otherwise, it will not start correctly. Please refer to the Strapping-Pin section of the ESP32-S3 datasheet for detailed information.
-
An SPI interface for a TFT display is reserved on the back of the module. The compatible FPC connector specifications are 8 PIN and 12 PIN.
