Next place the controller board on top, lining up the header pins to their spots on the controller board. Secure
the headers into place by soldering one pin on each one to the controller board, and then flip over and do the
same to the sockets on the LED board. Double check that everything is snug and seated well, and then proceed
to solder the rest of the pins.
Your assembly should look something like the picture below.

Step 2: The Power Jack
We‟ve got a couple more things to attach to the LED board and we‟re
done with soldering. Separate the LED board from the controller, and
place it LED-face down.
You may have noticed that there are a couple footprints for the power
jack (there‟s also one on the controller board, though we‟ve partially
covered it with the capacitors.) This was done to allow maximum
flexibility, and if your purposes call for it, the alternative placements
are functional. But for the standard build, we will use the footprint in
the middle of the PCB.
So solder that baby in. Your board should now look like the picture
below.
