Wiring Example

To wire a Common Cathode Seven Segment Display (like the 5161AS) to your Meadow board, connect the following:

SevenSegment	Meadow Pin
portE	D11
portD	D10
PortDecimal	D09
PortC	D08
PortG	D07
PortD4	D06
PortB	D05
PortD3	D04
PortD2	D03
PortF	D02
PortA	D01
PortD1	D00

It should look like the following diagram:
