ESP32-S3 DevKit

These boards are generally a good choice to run OpenDTU if you aspire to assemble your own hardware components. Have a look at the user guide.

Warning

Modules with 8 MB of PSRAM or 16 MB or more of flash memory use an octal SPI interface. On these modules, pins GPIO 35, 36, and 37, which are usually wired to the DevKit board's pin header, are in use for the internal communication between ESP32-S3 and SPI flash/PSRAM memory. Thus these pins are not available for external use, even though they are wired to the DevKit board's pin header.

Overview

The following is an overview of the original Espressif ESP32-S3 DevKit (USB-C version). Many modules offered on well-known larger Chinese or local web stores are usually merely compatible imitations.

Firmware

Use variant generic_esp32s3_usb on these boards. Three hardware UARTs will be available. Console messages will appear on the USB connector which is wired to the native USB stack of the ESP32-S3.
