What is the electrical component at A?
Any help would be appreciated!
A pair of pads may be ?
EDIT: they state on the web site for the 3.0 & 3.1 Schematic
A pair of pads are linked to join VUSB to VIN. For applications where external power is needed, these pads may be cut apart to isolate the board's VIN power from VUSB.
➜ so likely this
Awesome great thanks! Since its 3.2 I doubt its different in that regard
