ESP32-S3 module variant for target hardware

Since R2026b

Model Configuration Pane: Hardware Implementation / Hardware board settings / Target hardware resources / Groups / ESP32-S3 board properties

Description

Select the ESP32-S3 module variant installed on the target hardware board. The module selection determines the available GPIO pins, memory configuration, and supported peripherals. Different modules have different pin mappings, flash sizes, and PSRAM availability.

Dependencies

To enable this parameter, set Hardware board to ESP32-S3 Series (Arduino Compatible).

Changing this parameter updates the available entries in the Board parameter, as each module supports different development kit boards.

Settings
