The Terminal Block Breakout FeatherWing kit is like the Golden Eagle of prototyping FeatherWings (eg. majestic, powerful, good-looking). To start, you get a nice prototyping area underneath your Feather, with extra pads for ground, 3.3V and SDA/SCL. Not one to stop there, they expanded the PCB out to 2" x 2.5" with 3.5mm pitch terminal blocks down each side. There's also four mounting holes so you can attach the breakout to your enclosure or project.
This product works with all Adafruit's Feathers! The terminal blocks allow you to connect to any of the external Feather pins, great for wiring temporary or permanent installations. Adafruit also give you a few extra terminal block pins for ground and 3.3V connections since those are so useful.
Finally, there's a spot for soldering in a slide switch. This connect the EN pin to ground when in the 'off' position, cutting off the 3.3V regulator. Note that the FONA Feather uses both VBat and 3.3V as power supplies so you wont be able to fully turn off the FONA Feather with this switch.
Comes as a kit with a nice PCB, socket headers, terminal blocks, and a slide switch. Soldering is required to assemble the Terminal Block Breakout FeatherWing, but it's not too tough if you've got a soldering iron and some basic hand tools.
