Completed wiring of the Display SD card and the 3 keys that i will be using for navigation on the display. Even tho the display can have its own sd card but still i will be adding a microsd card slot on the main board so that it looks clean i can use a micro Sd card instead image.png

Soo i completed the power part of the circuit the board will have both 3.3v and 5v on board and wanted to add a extra thing which is the system will charge it elf and power the system simultaneously when i plug it in its called load sharing and it was my first time doing so so took me a lot of time figuring it out https://ww1.microchip.com/downloads/aemDocuments/documents/OTH/ProductDocuments/UserGuides/51746a.pdf image.png

I took refernce from the data sheet https://www.lcdwiki.com/res/MSP3520/MSP3520_Size.pdf and made symbol and footprint for the display to be used image.pngimage.png

I started out by charting the features I would like to have on that HUB since my aim is to getting a device with which i will use and control all my other esp32 web projects

other thing done is completing the basic circuit for ESP32 S3 and the programming IC which here is CH340C image.png
