Picked wrong blend of pins initially, need to update pin out and remake proto board wing

Notes

MUST use sercom 1, 2, 3 or 4
Check the wiring diagram for which sercom ports are safe
Check the below to ensure the right sercom pads are used for wiring

Pinouts (the S4:1 is a sercom) : https://cdn-learn.adafruit.com/assets/assets/000/046/244/original/adafruit_products_Feather_M0_Basic_Proto_v2.2-1.png?1504885373
