main/CMakeLists.txtESP32-S3 No-Connect Markers
Add no-connect markers to the unused pins of the ESP32-S3 module.
Thought for 12 sec
I’ll identify the ESP32-S3 pins with no electrical connections, add no-connect markers only to those pins, then verify the result.
Worked for 1 min 45 sec
Added no-connect markers to all 33 unused GPIO/UART pins on U1. Verified no connected, power, ground, EN, boot, or strapping pins were marked; existing wiring and placement remain unchanged.
Fix essentials and review
Connect ground pins
Add EN boot circuitry
Run ERC review
Arrange schematic

Firmware Getting Started
Minimal ESP-IDF starter for the ESP32-S3. No peripheral GPIOs are assigned.
Pin mapping
No GPIOs are assigned in this prototype.
Toolchain
Install ESP-IDF, then create the files below and build with:
Sh
idf.py set-target esp32s3 idf.py build
CMakeLists.txtCmake
cmake_minimum_required(VERSION 3.16) include($ENV{IDF_PATH}/tools/cmake/project.cmake) project(esp32_s3_prototype)
Cmake
idf_component_register(SRCS "main.c" INCLUDE_DIRS ".")
main/main.cC
#include "freertos/FreeRTOS.h" #include "freertos/task.h" void app_main(void) { for (;;) { vTaskDelay(pdMS_TO_TICKS(1000)); } }
Startup sequence
ESP-IDF initializes clocks, memory, FreeRTOS, and system services before calling
app_main(). This starter intentionally initializes no GPIOs or peripherals.Pin mapping
