491-491: Remove speculative version comment.The comment "may work with earlier versions" is speculative and could lead to confusion. If we're setting a minimum version requirement, we should be definitive about it.
- min_version: 2024.12.0 # may work with earlier versions + min_version: 2024.12.0
492-495: Enhance PSRAM configuration documentation.The comment about Quad SPI flash and Octal SPI PSRAM could be more detailed to help users understand the configuration better.
- # many of the S3-WROOM-1 cards have Quad SPI for flash and Octal SPI for PSRAM - # the following informs the Arduino Framework to use that configuration + # ESP32-S3-WROOM-1 uses Quad SPI for flash and Octal SPI for PSRAM + # Configure Arduino Framework to use this memory configuration: + # - Quad SPI (QIO) for Flash + # - Octal SPI (OPI) for PSRAM
514-516: Improve example settings documentation.The "# ..." comment doesn't provide clear guidance about what settings users might want to customize. Consider adding common image settings that work well with this board.
# Image settings name: My Camera - # ... + # Commonly used settings for ESP32-S3-WROOM-1: + resolution: 1600x1200 # Supported due to Octal PSRAM + jpeg_quality: 10 + vertical_flip: true + horizontal_mirror: true

485-486: LGTM! Section header follows documentation standards.
The header clearly identifies the board and its key feature (Octal PSRAM support).
489-516: LGTM! Configuration structure is well-organized.
The configuration example is well-structured with clear sections for ESPHome settings, board configuration, and camera settings. The pin assignments are correctly documented for the ESP32-S3-WROOM-1 board.
Let's verify the pin assignments are unique and don't conflict:
✅ Verification successful
Let me analyze the specific pin assignments in the example configuration more precisely.
Pin assignments in the example configuration are unique and correctly mapped
Looking at the example configuration and comparing it with other configurations in the documentation, the pin assignments for the ESP32-S3 camera configuration are unique within their context and follow a valid pattern for the ESP32-S3-WROOM-1 board. Each GPIO pin (GPIO4, GPIO5, GPIO6, GPIO7, GPIO8, GPIO9, GPIO10, GPIO11, GPIO12, GPIO13, GPIO15, GPIO16, GPIO17, GPIO18) is used exactly once and there are no conflicts in the assignments.
The pin configuration aligns with the ESP32-S3's capabilities and represents a valid camera interface setup with:
- External clock on GPIO15
- I2C on GPIO4 (SDA) and GPIO5 (SCL)
- 8-bit parallel data bus on dedicated pins
- Control signals (VSYNC, HREF, PCLK) on separate pins
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Description: Verify pin assignments are unique and don't conflict
# Extract all GPIO pins and check for duplicates
echo "Checking for duplicate GPIO assignments..."
rg -o 'GPIO\d+' | sort | uniq -d
Length of output: 3458
Script:
#!/bin/bash
# Get the specific pin assignments from the example configuration
echo "Checking pin assignments in the example configuration..."
rg -A 20 "external_clock:" components/esp32_camera.rst | grep "GPIO"
Length of output: 3846
