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 **[[https://docs.espressif.com/projects/esp-idf/en/latest/esp32s3/hw-reference/esp32s3/user-guide-devkitc-1.html#contents-and-packaging|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: [[https://docs.espressif.com/projects/esp-idf/en/latest/esp32s3/hw-reference/esp32s3/user-guide-devkitc-1.html#description-of-components|Espressif ESP232 DevKitC user guide]])

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