Step 8: Solar charger circuit

Next we'll install the solar charger circuit. The process is similar to the last step.

1. Place the solar charger circuit so that the black barrel jacks stick out the DC port bezel, and the 4 holes on the circuit board align with the screws. (Important note below)
2. Grasp the enclosure and circuit board as shown in the picture
3. Tighten the 4 screws (make sure the screws are engaging the holes in the circuit board).

Update: Some kits have shipped with bezels that were not cut to the correct dimensions. As a result, the barrel jacks may not go through the port openings very easily. One solution is to file away a bit of material off the top of the barrel jack, or to use the sand paper or a knife to make the port opening a bit taller. In either case, only about 0.5mm (1/32") needs to be removed.

Instead of using the provided wood type screws, I would recommend on swapping them out with machine screws with nuts. While it might be tricky to get the nuts in there, you would end up with a better secured board.
