Prepare the header strip:

Cut the strip to length if necessary. It will be easier to solder if you insert it into a breadboard - long pins down

Add the FeatherWing:

Place the featherwing over the pins so that the short pins poke through the two rows of breakout pads

And Solder!

Be sure to solder all pins for reliable electrical contact.

(For tips on soldering, be sure to check out our Guide to Excellent Soldering).

Start by soldering the first row of header

Now flip around and solder the other row completely

You're done with the two header strips.

Check your solder joints visually and continue onto the next steps

Next we will solder in the larger header blocks used to plug in servos into the FeatherWing. There are two block, each are 3x4 headers in size.

The go on either end. Make sure the long side of the headers is facing up!

To make it easier to keep these in place, you can use some tape to hold down the two header pieces. Tacky clay also works, whatever you've got handy!

Solder in each block, make sure you get to each of the 12 pins

Now that you're done with the header blocks, check your work make sure that each solder joint is done and looks shiny.

Last is the 3.5mm terminal block used for power. This is how you will provide the large amount of current that servos require.

Make sure the two open parts of the terminal face outwards so you can easily connect wires

Solder in both pins of the terminal block. You can remove the tape when done.

OK You're done! You can now plug in your FeatherWing into your Feather and get servo'ing
