The Adafruit FeatherWing Doubler Prototyping Add-ons let you work on a Feather main board and another board at the same time, side by side. The boards are supplied with stacking headers so you could also plug the Doubler into a Feather main board and work on two FeatherWings boards. This is a board you're going to want in your toolbox because there's guaranteed to be a situation when you want to get at the middle board of a stack. The boards have two sets of Feather pins which are cross connected giving you two identical Feather footprints. They also have a double row of power pads (3.3V and Gnd) plus two grids of unconnected pads giving you two mini-breadboards. The Feather pins are available even when you've soldered in the headers so that you can have prototype circuitry directly on the Doubler PCB and stack a Feather or FeatherWings on top. Phew!
Supplied as bare board with strips of 0.1in. pitch stacking female headers and 0.1in. pitch female headers for you to solder on as required.
