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
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
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!
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
