Doubler Pinout

The Doubler Featherwing is fairly simple. It's 2.0" x 1.9" - the same as two proto Featherwings side by side with a 0.1"

spacing in between (since there's slight variations on PCB routes, you dont want to have no spacing between them or

plugged-in-feathers might jam)

Duplicated IO Pins

On the outer edges are all the pins you'd want to solder in to connect to the Feather. The inner set of pins are boxed

and have small text or dots to indicate they are connected. They are tied together so you have access to each I/O pin!

Also, both sets of IO pins are connected together
