Support for the ESP32-S3-Box.
The Espressif ESP32-S3-Box is a AIoT development platform for the ESP32-S3 SoC.
The ESP32-S3-Box has following main features:
|16 MB Flash||yes|
|8 MB Octal SPI RAM||yes|
|2.4" LCD Display 320 x 240 with ILI9342C||yes|
|Capacitive Touch Panel||no|
|Dual Microphone ES7210||no|
|Speaker Codec ES8311||no|
|3-axis Gyroscope, 3-axis Accelerometer||no|
|2 x Digilent Pmod(TM) Connectors||yes|
The Espressif ESP32-S3-Box is shipped with a Dock which exposes the 2 x Digilent Pmod(TM) Connectors.
This section describes
Most features of the ESP32-S3-Box are provided by the ESP32-S3 SoC. For detailed information about the ESP32-S3 SoC variant (family) and ESP32x SoCs, see section ESP32 SoC Series.
The following table shows the default ESP32-S3-Box configuration, which is sorted according to the defined functionality of GPIOs. This configuration can be overridden by application-specific configurations.
|BUTTON0||GPIO0||Boot Mode Button|
|I2C_DEV(0) SCL||GPIO40||PMOD1||I2C Interfaces|
|I2C_DEV(0) SDA||GPIO41||PMOD1||I2C Interfaces|
|SPI_DEV(0) CLK||GPIO12||PMOD2, SPI2_HOST (FSPI) is used||SPI Interfaces|
|SPI_DEV(0) MISO||GPIO13||PMOD2, SPI2_HOST (FSPI) is used||SPI Interfaces|
|SPI_DEV(0) MOSI||GPIO11||PMOD2, SPI2_HOST (FSPI) is used||SPI Interfaces|
|SPI_DEV(0) CS0||GPIO10||PMOD2, SPI2_HOST (FSPI) is used||SPI Interfaces|
|SPI_DEV(1) CLK||GPIO7||LCD SCK, SPI3_HOST is used||SPI Interfaces|
|SPI_DEV(1) MISO||GPIO35||not used, SPI3_HOST is used||SPI Interfaces|
|SPI_DEV(1) MOSI||GPIO6||LCD SDA, SPI3_HOST is used||SPI Interfaces|
|SPI_DEV(1) CS0||GPIO5||LCD CS, SPI3_HOST is used||SPI Interfaces|
|UART_DEV(0) TxD||GPIO43||PMOD2||UART interfaces|
|UART_DEV(0) RxD||GPIO44||PMOD2||UART interfaces|
The following figures show the pinouts as configured by default board definition.

Since the ESP32-S3-Box does not have a USB-to-Serial chip, the easiest way to flash it is using the USB Serial/JTAG interface. Just connect the ESP32-S3-Box to your host computer and use the following command:
Usually the make system resets the ESP32-S3-Box before flashing to enable the USB Serial/JTAG controller and to reboot the ESP32-S3 in download mode.
In some very special cases this reset does not work and the programmer cannot connect to the card, so the flashing is aborted with a timeout:
This can happen either if RIOT is not yet installed or if the USB port was previously used with the USB OTG controller, for example with USBUS or tinyUSB. In this case, restart the ESP32-S3-Box manually into download mode by pressing and releasing the RESET button while holding down the BOOT button. In download mode, the USB Serial/JTAG interface is always available.
