-- This application can run on ESP32 and ESP32-S3 boards which will function as a debugger.
-- PSRAM is necessary for both boards.
-- We recommend using ESP32-S3 for improved performance.

+- PSRAM is necessary for the ESP32-S3 boards.
 - Make sure to adjust Flash and PSRAM spi modes (DIO, QIO, OPI) from the menuconfig.
