## Description

This is the **FeatherWing Doubler** - a prototyping add-on and more for all Feather boards. This is similar to Adafruit's [FeatherWing Proto](https://core-electronics.com.au/featherwing-proto-prototyping-add-on-for-all-feather-boards.html) except there are two! The magic of the Doubler comes when stacking a Feather and another board on top of the Doubler so you can work with both boards simultaneously side-by-side! In addition to the board the Doubler comes with:

- 1 Doubler PCB
- 1 set [Feather Stacking Headers](https://core-electronics.com.au/feather-stacking-headers-12-pin-and-16-pin-female-headers.html)
- 1 set [Feather Female Headers](https://core-electronics.com.au/feather-header-kit-12-pin-and-16-pin-female-header-set.html)

The Doubler, like the Proto, has a duplicate breakout for each pin on a Feather, as well as a bunch of plain grid proto holes. **Also, the two sets of pins are cross connected** and for GND and 3.3V, Adafruit give you a full strip of connected pads.

**You'll need to solder on the female headers or stacking headers however you like,** the Doubler comes as a mini kit!
