ESP32-S3-DevKitC-1 V1.1 by Espressif

Naming convention:
ESP32-S3 : microcoltroller core or variant
DevKitC : form factor of the microcontroller board
-1 : based on WROOM-1 module soldered onto the circuit board
V1.1 : the hardware version / revision

The ESP32-S3-DevKitC-1 is a general-purpose development board, based on ESP32-S3-WROOM-1, ESP32-S3-WROOM-1U, or ESP32-S3-WROOM-2. All ESP32-S3 pins are exposed to the board's pin headers. The mounted modules WROOM-1 and WROOM-2 differ in their memory sizes. The U-variant provides an antenna connector for an external antenna instead the integrated one.

The AMC SS2024 course utilizes the development kit variant ESP32-S3-DevKitC-1-N8R8 V1.1.
Specs:

ESP32-S3 WROOM-1 module with integrated antenna
8 MB flash memory (for program code) connected via Quad SPI (QD)
8 MB external PSRAM (for variables during program execution) connected via Octal SPI (OT)

“For boards with Octal SPI flash/PSRAM memory embedded ESP32-S3-WROOM-1/1U modules, and boards with ESP32-S3-WROOM-2 modules, the pins GPIO35, GPIO36 and GPIO37 are used for the internal communication between ESP32-S3 and SPI flash/PSRAM memory, thus not available for external use.” (Source: Espressif ESP232 DevKitC user guide)

Therefore, AMC students: Do not use GPIO35, GPIO36 and GPIO37! (When you use the ESP32-S3-DevKitC-1).
