As soon as the custom PCB came back, I immediately noticed that I've made a few small mistakes:

1. The back silkscreen LED names got messed up
2. I should have made the SAO pin labeling on the top silkscreen instead of bottom as having it on the bottom would be covered by the header itself.

Not to worry, these mistakes are only cosmetic and don't mean game-over yet. Hopefully it can still help me see if my concept works or not.

If I am to mass produce these for the Hackaday Supercon 2024, I still have time for ONE more iteration if I work hard. But that iteration would have to be final final, otherwise I'm not going to make it.
