- Side that is more beveled is where pin 1 is
- Incorrectly oriented the first one, bought a heat gun to de-solder and re-orient it
- Bought isopropyl alcohol pcb cleaner to clean flux and solder residue
- Organized bags containing surface mount parts by number of the first component
- Attached Audio Jack:
