Teensy MCU in Altium

BLUF - I used learned how to use Altium to design a PCB to control LEDs

Using Altium, I made a schematic and PCB of a Teensy with 20 devices (LEDs). What I love about EE is its practicality and organization: Each component has a specific purpose, where only what is needed has a spot on the board, and vias are placed to improve grounding and reduce noise. Traces must be compactly routed with minimal length and not intersect.
