+Either way, you can now solder the power jack connector and JST-XH 3-Pin connector (if desired) onto the base.

+The power jack connector goes on the top of the base, the same side as the sockets.

+The JST-XH 3-Pin connector goes on the bottom of the base, the opposite side as the sockets, on the "DIN" pins.

 #### LED Sticks
 
 1. Your LED strips may come all connected in one PCB piece. If so, you'll need to carefully and gently separate them along the scored lines.

+#### PixelBlaze & Sensor Expansion Assembly
+
+Pixelblaze output:
+
+1. Place the 4 pin JST-XH connector into the holes on the left side of the Pixelblaze (GND, DAT, CLK, and 5V).
+1. Flip it over and solder all four pins.
+
+Pixelblaze expansion pins:
+
+1. Place the 7 pin header that came with the Pixelblaze Sensor Expansion in the holes in the bottom right corner of the **Pixelblaze**, not the expansion board. Note that the GND, RST, 3v3, RX, TX, IO0, and IO25 should have pins, and that IO26 will not have a pin.
+1. Ensure the 7 pin header is inserted all the way down, and that there are pins in the GND, 3v3, and RX holes on the Pixelblaze.
+1. Flip the Pixelblaze over and solder at least the GND, 3v3, and RX pins.
+
+Pixelblaze Sensor Expansion Board:
+
+1. With the Pixelblaze right-side up, with the pins pointing upwards, flip the Sensor Expansion Board over so the audio input jack is on the bottom, pointing down.
+1. Place the sensor board onto the Pixelblaze pins.
+1. Ensure that the GND, 3v3, and RX pins on the Pixelblaze are lined up and inserted into the GND, 3v3, and TX pins on the Sensor Expansion board. Note that the TX pin on the Sensor Expansion board is connected to the RX pin on the Pixelblaze
+1. The top of the audio input jack should be flush with, and not extend beyond the bottom of the Pixelblaze PCB.
+1. Double-check the pins are aligned and match up one more time.
+1. Solder at least the GND, 3v3, and TX pins on the Sensor Expansion board.
