This tutorial concerns the CC1333 board cam and its corresponding plastic case. They are available to buy in our shop here:
PLEASE NOTE: If you have bought your board cam from HobbyRC and decide to cut it down to fit in our plastic case, you will be invalidating the warranty since this is a destructive process. This tutorial is provided purely for informational purposes and you undertake the installation at your own risk.

As always, lay out all the parts and tools you will need in front of you before you begin. In addition to the CC1333(B) Board Cam and the Plastic Case, you will need a tool for snipping the board cam's PCB (we used a pair of wire cutters), a small Phillips head screwdriver and some sandpaper for cleaning up the edges of the PCB (not pictured).
The PCB comes with holes for two mounting options - 34 x 34mm and 28 x 28mm. The first step is to remove the outer portion of the PCB leaving only the 28 x 28mm holes in order to make it fit into the plastic case.
Before cutting anything it is important to ensure that you keep the protective cover on the lens to prevent any damage. You should also take every precaution not to damage any components on the PCB during the process.
Carefully cut off the long strips which run along each side of the PCB. Once you have done this, you can more easily remove the remaining material on the corners. You can offer the board cam up to the plastic case to see whether it fits at this point and continue sanding until it does. Take a little time to remove any loose material and make sure the edges are finshed smoothly.
It is better to cut off a little less material than you need to and then file and sand it down rather than cut off too much. Make sure you have cleaned the PCB and your work area before moving on. You will be exposing the image sensor and the inside of the lens assembly both of which are very sensitive to debris.
Once you have trimmed down your board cam, you will need to remove the lens assembly from the PCB. Remove the two small screws on the underside of the board, keeping them to one side:
Once again, it is very important not to touch the image sensor or the inside of the lens assembly as they are both very sensitive to debris.
Now you have removed the lens assembly, you can install the PCB in the plastic case. The back cover of the plastic case has a specific orientation which aligns with the pins on the PCB. Make sure that when in the case, the cover fits on with the writing reading left to right. This way your image should remain aligned with the horizon as you would expect (obviously, the case allows for the camera to be flipped vertically). Use four of the longer screws provided with your case to attach the back cover onto the main housing.
The opening on the front of the plastic case which aligns with the image sensor is threaded - this is where the lens assembly fits. Separate the two parts of the lens assembly and screw the part which contains the lenses into the plastic case as shown below:
The plastic ring on the lens assembly is used to limit the range of movement on the thread and focus the lens on the image sensor - you will need to adjust this yourself to find the optimum position.
Your board camera is now installed and ready to fit onto your multirotor.
