PCB Routing + Finish PCB Design

I routed the PCB together and I finished the PCB design. Now I need to create the case in CAD software, then write the firmware. Hopefully I can finish both tomorrow.

To route the PCB, I used 2 layers. The OLED, switch matrix, and rotary encoder are all on the front, while the microcontroller and diodes are in the back. This allows me to have a more clean design.
