The circuit for the necklace will be done just as the wiring for the "Test OLED Display", except the JST battery extension cable will be added with its male end removed.
OLED -> Pro Trinket
- Gnd -> G
- Vin -> 5V
- Data -> Digital 9
- Clk -> Digital 10
- D/C -> Digital 11

No caffeine and make sure you read the "Solder Circuit" section first!
