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, we 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.
The terminal blocks allow you to connect to any of the external Feather pins, great for wiring temporary or permanent installations. We 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.

The Terminal Block Featherwing doesn't have any active components. Instead, it just breaks out all the existing connections from a Feather. Note that Feathers use different
chipsets so not all pins are labeled on purpose!
The only pins you can depend on are:
•
3.3V power
•
3.3V enable
•
VBat power

USB power
GND

I2C: SDA & SCL
SPI: MOSI, MISO, SCK
UART: RX & TX
Check your Feather documentation and product page for details on what other pins are available and what they are connected to

Start by grabbing the blue terminal blocks. Terminal blocks
only come in 2 and 3 pin sizes, but can be slid together to form

longer strips. Start by connecting a 2 and 3 pin piece together.
There's nubs on either side so line those up and you'll be able to
slide them together
•
Keep sliding more 3-pin blocks on until you get a 2-pin block
with four 3-pin blocks in the middle and then another 2-pin
block at the end
