This assignment is designing a PCB for a microcontroller

I really had to spend a lot of time just understanding the assignment, I wasn't sure if we were using the microcontroller boards we were given or if we are to use the actual microcontrollers. I also wasn't sure what the possibilities were. I spent multiple days thinking about what I wanted to make and why.
I wanted to use the ESP32-CAM, so I can make a DJ USB that streams video from itself

I wasnt sure what all the already added components where so i asked chatGPT
The ESP32-CAM doesn’t come with a USB connector, so you need an FTDI programmer to upload code through the U0R and U0T pins (serial pins).
I started off using Hello wold on PCBSVG
this design already had the header_FTDI which allows a connection to FTDI programmer I wanted to add a nice place for the omnivison OV2640 2 megapixel camera to connect to

this also uses the I2C COMMUNICATION PROTOCOL. I used this website to learn about it: https://www.circuitbasics.com/basics-of-the-i2c-communication-protocol/
you can see how i wander about in this world

I asked chatgpt about how to connect a camera to the the ESP32 CAM, it led me astray

I'm not sure if this information is correct, but the information that I needed was that it has a gold plated connector strip built in that fits the OV2640. I learned that from this video
but before I knew that i found the OV2640 kicad_mod to download into SVG PCB. I decided to leave it in the schematic to illustrate it is there even though the ESP32-CAM mod doesnt list the connector strip.

next I need to add USB interface so that it can be plugged into a CDJ.
I looked online and everyone seems to be using this FT232RL
C1 and C2 are decoupling capacitors to reduce the supply noise
I was having trouble during the routing to not have the wires cross
I ended up flipping the USB out, as that solves most USB related connection issues

My final design!

The code:
