Overview

Once you've got your Feather board up and running you probably want to have some custom circuiry attached. Of

course, you can start with a breadboard setup and that will work just fine for prototyping. But, once you know what you

want, a proto feather can keep the components compact and secure.

We have

three options

for prototyping, all are "FeatherWings" - add on boards that can be plugged right into any

Feather.

FeatherWing Proto

First is the FeatherWing Proto - a prototyping add-on for all Feather boards. Using our Feather Stacking

Headers (http://adafru.it/2830) or Feather Female Headers (http://adafru.it/2886) you can connect a FeatherWing on

top or bottom of your Feather board.

This has a duplicate breakout for each pin on a Feather, as well as a bunch of plain grid proto holes. For GND and

3.3V, we give you a strip of connected pads. There's plenty of room for buttons (https://adafru.it/dSh),

indicator LEDs (https://adafru.it/dLA), or anything for your portable project. The FeatherWing Proto makes an ideal

partner for any of our Feather boards.

FeatherWing Doubler

If you need even more space, or maybe you want to have two wings plugged in at once, you can double your

prototyping space with a FeatherWing Doubler. Using our Feather Stacking Headers (http://adafru.it/2830) or Feather

Female Headers (http://adafru.it/2886) you can connect a FeatherWing on top or bottom of your Feather board.

This design also has duplicate breakout for each pin on a Feather, as well as a bunch of plain grid proto holes. For

GND and 3.3V, we give you a strip of connected pads. The I/O pins are 'connected through' between the two sides

with skinny 10mil thick traces that pass through the 0.1" grid holes so you can plug a Feather into one side and you get

a fully connected set of headers on the other side

FeatherWing Tripler

Need MOAR space? Get 50% more than a Doubler with the Tripler!

This is similar to our FeatherWing Proto (http://adafru.it/2884) except there are three! The magic of the Tripler comes

when you want to connect your Feather to two other Feather Wings without needing any stacking headers!

This design also has duplicate breakouts for each pin on a Feather, as well as a bunch of plain grid proto holes. For

GND and 3.3V, we give you a strip of connected pads. The I/O pins are 'connected through' between the two sides

with skinny 10mil thick traces that pass through the 0.1" grid holes so you can plug a Feather into one side and you get

two fully connected sets of headers on the other side

Proto Pinout

The Proto Featherwing is fairly simple. It's 2.0" x 0.9" so it fits right over a feather.

Duplicated IO Pins

On the outer edge 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. The above shows the outer and inner set of pins. They are

tied together so you have access to each I/O pin!

Power Rails

You also have two strips of holes that are all connected for 3.3V (left strip) and GND (right strip). This way you have

plenty of power/ground connections available. The holes are 0.047" diameter and are connected with 24mil traces.

Proto Grid

Finally, there's a full set of prototyping grid, each hole is 0.047" diameter

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

Power Rails

You also have two strips of holes that are all connected for 3.3V (left strip) and GND (right strip). This way you have

plenty of power/ground connections available. The holes are 0.047" diameter and are connected with 32mil traces.

Note there's a thin strip of proto holes in between the 3V and GND rails

Proto Grid

Finally, there's a full set of prototyping grid, each hole is 0.047" diameter

Note there's a thin strip of proto holes in between the 3V and GND rails

Tripler Pinout

The tripler pinout is pretty much the same as the doubler. There's just one extra footprint. So look there for pinout info.

I'm missing some of the copper traces on the back.

If your tripler looks like the one below, then it's OK. The copper traces are still there, and if you look close you

should be able to see them. The solder mask in these areas just didn't get removed for some reason. This is just a

cosmetic issue and does not affect functionality.

Assembly

When putting together your Proto or Doubler Featherwings, think about how you want it to connect, you can use

stacking headers:

Or plain female socket headers:

The most common method of attachment for the Proto is putting stacking or female headers on the Featherwing and

then putting the Proto on top:

But don't forget, you can also put the stacking headers on the Proto wing and stack the Feather on top of it!

For the Doubler, you can use it side-by-side

By soldering female or stacking headers onto the doubler, but you could also have mulitple stacking wings.
