Hey! this is an awesome devboard but there is one tiny issue: Your USB-C should be placed on the edge of the board. Right now the way its placed you won't be able to plug a usb cable!
Additionally you should also have a BOM file at the root of your repository and at the end of the Readme in a table format. https://blueprint.hackclub.com/about/submission-guidelines
ps: you should also try use netlabels to tidy up your schematic! it makes it easier for other people to read and catch mistakes in. Feel free to ask for help in #blueprint on how to use netlabels and make a clean readable schematic

Hey, it looks like you submitted two different screenshots for your shipping option - can you just specify which one you're going to end up ordering with? I assume it's E-Post, which is fine. Also make sure to attach a screenshot options page that shows how many layers and other things you can choose to cutomize your pcb! Other than these two things, your devboard looks great!

Completed PCB | Ready to Ship
So I have completed the PCB. I placed some designing elements onto it and also added text with each pin to tell which pin it is. It was difficult because I forgot how I did pin placement. After this, I took quote from JLCPCB and cost is about $100 and hopefully I can get it as its usually a Tier 3 Project. Most of time was spent on JLCPCB fixing the BoM and CPL etc

Made and Routed the PCB
So I have successfully made the PCB and also routed it. Everything was too easy from placing components inside a rectangular kindof boundary of the ESP32 but the main issue came with routing. The routing was very difficult due to several connections so I have to use a lot of vias and have to retry a lot times. IT WAS VERY DIFFICULT TO ROUTE EACH AND EVERY CONNECTION EVEN IF I TRIED ON DIFFERENT LAYERS. It took a lot of tries but at the end, finally I have a complete PCB. Now I will just brand the PCB a bit and then submit project. I am thinking of creating a 3D Case for it but its not confirmed yet

Completed the Schematic Diagram
So I have successfully completed the schematic diagram. It was very difficult because it became messy but somehow I figured it out. Thanks to the online guidance that helped me route pins correctly (T-T)

Created BoM | Started Schematic Diagram
So I came to know that am not required to mention the product link and cost in BoM because I will be ordering PCBA so the only cost will be of PCBA so I completed the BoM by mentioning all products and their quantity and writing a small not about it. After this, I started creating schematic diagram. It was difficult to find the symbols but succesfully I did. After this I have made the schematic of one side of the ESP32 S3 WROOM 1 Chip and its top and bottom pins/ports.

Started making the BoM | Went Wrong (T-T)
So I started creating BoM. Firstly I decided which raw chip to use. I initially planned to use ESP32 P4 but later shifted to standard S3 WROOM 1 Chip. I started listing the things I required and also adding its link with it and the cost too. But then I got hit by realisation that I am going to do PCBA so why am I giving links to source components. So I have stopped creating BoM and left it incomplete. I will proceed after getting answer to my query in Slack.
