============== ESP32S3-DevKit ============== The `ESP32S3 DevKit `_ is a development board for the ESP32-S3 SoC from Espressif, based on a ESP32-S3-WROOM-1 module. .. list-table:: :align: center * - .. figure:: esp32-s3-devkitc-1.png :align: center Features ======== - ESP32-S3-WROOM-1 Module - USB-to-UART bridge via micro USB port - Power LED - EN and BOOT buttons (BOOT accessible to user) - SPI FLASH (size varies according to model Serial Console ============== UART0 is, by default, the serial console. It connects to the on-board CP2102 converter and is available on the USB connector USB CON8 (J1). It will show up as /dev/ttyUSB[n] where [n] will probably be 0. Buttons and LEDs ================ Buttons ------- There are two buttons labeled Boot and EN. The EN button is not available to software. It pulls the chip enable line that doubles as a reset line. The BOOT button is connected to IO0. On reset it is used as a strapping pin to determine whether the chip boots normally or into the serial bootloader. After reset, however, the BOOT button can be used for software input. LEDs ---- There are several on-board LEDs for that indicate the presence of power and USB activity. None of these are available for use by software. Configurations ============== nsh --- Basic NuttShell configuration (console enabled in UART0, exposed via USB connection by means of CP2102 converter, at 115200 bps).
