ESP32-S3 Boards

There are several boards available using the ESP32-S3 chip. Boards based on the ESP32-S3 variant offer a high performance dual core SoC with vector hardware acceleration and special display interfaces.

The ESP32-S3 variant of the ESP32 is supported by the espressif ESP32 Board package and by the Homeding library.

The Arduino ESP32 Board package supports the Arduino Nano ESP32 board only.

The ESP32-S3 is based on the Xtensa 32-bit LX7 single or dual-core processor that operates at up to 240 MHz.

It offers:

This SoC is positioned as a high-power SoC MCU with Wi-Fi and Bluetooth 5 (LE) for general purpose devices. The built-in LCD interface allows fast display performance.

It is part of some modules that offer PCB antenna or antenna connectors.

The official Arduino Nano ESP32 is based on this processor using a custom Module from U-BLOX.

Flash and PSRAM Memory options

Some versions of the chip offer an internal 4 MByte Flash ROM and/or internal PSRAM.

USB and JTAG Support

The ESP32-S3 SoC directly supports USB and USB OTG ports and also has a built-in JTAG adapter for debugging. Some boards still come with a USB to Serial chip.

Using a board with a USB to Serial chip

When you find a USB to Serial converter on the board the configuration for the USB features in the ESP32-S3 SoC must look like:

Using a board with direct USB connectivity (CDC mode)

These boards offer a USB connector that is connected to the GPIO19 (D-) and GPIO20 (D+). The configuration for the USB features in the ESP32-S3 SoC must look like:

When you find a USB to Serial converter on the board the configuration for the USB features in the ESP32-S3 SoC must look like:

To use the USB port as Serial port the CDC on boot option must be enabled in the Arduino configuration.

Bluetooth LE

The ESP32-S3 supports Bluetooth LE , Bluetooth 5 and Bluetooth mesh.

Bluetooth support is not yet given by the HomeDing library.

Powersave modes

several sleep modes:

Watchdog timer

Cryptographic Hardware Accelerators

Secure communication, signing packages and flash memory is supported by some built-in special functionality.

This results in faster secure (https) network requests.
