Hello, I just purchased all the components for the Aura project and approved the $25 payment to your account. I have a question: could you provide me with the initial project documentation so I can start assembling the system and testing the initial software? I've downloaded the Aura GitHub but I can't figure out how to configure this project. Do you have any more easily described documentation for starting the project? I don't have enough Arduino experience to properly implement this... perhaps by setting up ready-made BINs in the ESP.32 BIN uploader? |

Same for me! I am familiar with building firmware platforms, but prefer to use compiled packages if available. Could you also send me some of the preliminary documentation? EDIT: No need for the firmware files, managed to get it building & uploaded to the waveshare board. Did a quick test run with the SEN66 sensor and that is already working! Can't wait for the STL files to put all this in an enclosure! :) |

Same for me. I'm confused on how to start and load the initial firmware/software. Where can I find the steps for this????? |

Open the assembly instructions — everything is explained step-by-step, including how to flash the firmware using the web installer. |

Not to be snarky, but where are these instructions? That's what I'm looking for. All I've found is the brief steps shown at the bottom of the projects main webpage. That's not it is it? |

VS Code throws this error *** missing SConscript file 'C:\Users\user\.platformio\packages\framework-arduinoespressif32-libs\esp32s3\pioarduino-build.py' |

This is a local PlatformIO package-cache issue, not a project code issue.

Yeah I tried that a few times, but also looks like I got the 8MB version - https://www.amazon.com/dp/B0CNCRZWVB?ref=ppx_yo2ov_dt_b_fed_asin_title |

That's unfortunate — yeah, that Amazon listing is the 8MB Flash version, which won't work with Project Aura without major modifications. |

my error had something to do with long filenames I guess cause I put my project codes in my "my documents" folder it hit a character limit, I had to run powershell -Command "New-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Control\FileSystem' -Name 'LongPathsEnabled' -Value 1 -PropertyType DWORD -Force" to enable long file names Now it complied. :) |

Just tried to build/dl this project onto the Waveshare board I have (same as in your description). But when I run "pio run -e project_aura -t uploadfs".... It fails telling me the following: "A fatal error occurred: File .pio\build\project_aura\littlefs.bin (length 3538944) at offset 13172736 will not fit in 8388608 bytes of flash. Change the --flash_size argument, or flashing address. What am I doing wrong? Or is there something I have to change in your build scripts. FYI, I'm running PlatformIO Core (via pio) on a Windows 10 machine. Thanks in advance. |

You're absolutely right that 8MB Flash variants exist (I found them in the official Waveshare Wiki documentation) Sorry it didn't work out with your board |

Returning the board isn't an option... since I bought it back in 2024 (so probably a V1.0 board)... I think I'm outside the return window. Anyway, thanks for your responses and it is an interesting project. |

recheck your board, their may have been files preloaded on the flash that you can delete. i have the same board and it has 10.9 mb free |

If your chip says MCN16R8 then it should be 16mb unless its a counterfeit. check the wiki, you can change the partition table from 8 to 16. |

That's really interesting! Please let us know the results after you check with esptool.py flash_id — I'm curious if it's actually 16MB physically. |

I was able to flash to this board - https://www.amazon.com/dp/B0CNCRZWVB?ref=ppx_yo2ov_dt_b_fed_asin_title, salmod12 is right I wonder if you previously flashed something to it and it changed the partition sizes |

Just to confirm — when you ran esptool.py flash_id, did it report 16MB physical flash size, or did it actually show 8MB? |

I bought that board but my chip shield is laser etched with mcn16r8 and confirmed it with the ESPconnnect tool. If it says n8r8 then it is 8mb physically. |

@salmod12 Got it — so if the chip is marked MCN16R8, it's physically 16MB and should work fine with Aura's firmware. If it's N8R8, then it's actually 8MB and won't fit the current partition layout. |

FYI, on my board, the ESP32 case is etched with N8R8.
So, I definitely don't have 16MB flash.

@freshfitz <https://github.com/freshfitz> Can you check the chip marking
on your board? That should confirm whether you have 16MB or 8MB hardware. 👍

The initial ESP32 (was 8 GB) board I purchased was from the Waveshare shop at Amazon. Since it hadn't been that long I was able to return it and purchase the correct 16GB one from the same location. Thanks for identifying it so quickly. I was able to source the Adafruit breakout board from DigiKey. It is the Adafruit cables #4528 & #5754 that are on back-order that will be shipped later this month from DigiKey. There are some shorter and longer #4528 cables available but wasn't sure if they would fit so waiting on the back-order. The SFA30 sensor and screw terminal boards appear to be delayed since Seeed Studio hasn't shipped yet and no ETA. Thank goodness they are optional. |

Once I get all of the parts where do I start? It's not clear to me which files I need to download from Github and how I load them on the waveshare? |

This is a crowdfunding project with paid access to the files. The 3D printable files, assembly instructions, and firmware installer are available to backers who supported the campaign. |

This is what is described on the page:
📧 Assembly Instructions:
You should have received an email with a link to the assembly instructions
ZIP file. As a backup, I've also uploaded it to the model files — click
"Download STL/CAD Files" and you'll find the instructions archive there!
At the top of the page click "Download STL/CAD Files"
There will be included the instructions in a zip file...

Ahh. Thank you. That email must have been thrown in the spam folder, as I never got it. But I found the instructions as you mentioned in the STL/CAD files. I had previously only downloaded the 3mf file which didn't include the instructions. |

You're welcome.
I saw the message many times and I thought I will answer it for you ;-)
Right now I am checking if I have all the parts complete, and then
ensemble!!
I've printed most parts out of PA6-CF20 filament, looks pretty nice and
very strong.
Top cover printed in PETG.
Thanks for this awesome project, I love it!!
