Finished the PCB layout and made some final schematic updates.

While making the PCB I realized I didn’t have any decoupling capacitors, and since I’m using 20 addressable LEDs, changing them all at once might cause voltage drops and other unexpected issues so I added one 100nf capacitor per 2 LEDs.

The PCB layout took longer than expected. I had to learn about vias, ground planes, and different constraints. Routing everything on the 2 layer board took a while and a lot of trace reroutes.

Looking at the 3d model of the PCB I can see the macropad slowly coming together. The next step is to design the case around the PCB in Fusion 360.
