Final Folder Structuring and Push to Github
Spent some time finding better deals for components, organized files accordingly, reviewed all of the files and looked for errors. Took images and renders for Github. Wrote the readme file in plain text. Pushed to github. Added good formatting to the readMe.Md.

Firmware
I made the firmware after school and writing this later.
Fully made the firmware for both of the sides. Using left as the peripheral brain and right side as the brain.I made it so left side sends the input details to the right and right brain inputs it.Had some issues but solved all of them. Only problem is couldn`t test it yet so not 100% sure with the firmware

Sourcing
I've been busy with building my Hackpad.
To build the keybaord I need to source parts.
for now i have found 90% of the parts. Still have to find 2-3 components. I have made it cheap as possible its now sitting at ~80-90 usd

Changed to PCB
After redoing everything I have completed the core PCB. Now I gotten the shape the layout and fully routed. This means I only have to get it produced. But before that I want to customize it with silkscreen even though its going to be covered by the Keys>

Found a whole mistake and bug
When I was routing the PCB, I found a major flow with the diodes being connected. So I has to redo the project from the beginning. I also researched online to avoid future mistakes. I decided on using scottokeebs for the best components and the footprints.
I redid the entire schematics from the beginning

Finished Schematics and Assigned footprints.
I have completed the schematics part of the keyboard. I have also assigned the corresponding footprints as well.
Completed Schematics: Placed all components of the Keyboard. (Battery Sense, Testing pads, etc)
Assigned Foorprints: Assigned all of the footprints for components. I went with the cherry MX style switched

Starting schematics
I have started the project wired the XIAO and the key matrix.
Placing Footprints: Placed the XIAO MCU, Switches and the diodes. Followed the proper pin matrix.
Wiring them up: Wired the MCU and the pins accordingly
